Interview: Matte Vandeven on 20 Years of Sound of Liberation, My Sleeping Karma’s Return, and More
Posted in Features on March 6th, 2025 by JJ KoczanIn my defense, there was a lot to talk about with Matte Vandeven. Between 2025 being the 20th anniversary of the booking agency he founded, Sound of Liberation, and the return to the stage of his band, My Sleeping Karma, after suffering the loss of drummer Steffen Weigand in 2023, the near-unmatched impact Vandeven has had on the European heavy underground particularly with the emergence of a heavyfest culture he’s helped foster over the last decade and a half through close involvement with events like Desertfest Berlin, Up in Smoke, Keep it Low (celebrating its 10th edition this year), Blue Moon Festival, Lazy Bones Festival, Desertfest Belgium and others, the growth in the last few years of Sound of Liberation‘s label wing, SOL Records, and generally wanting to pick his brain about bands, what he listens for in a new artist, and so on? You can see why it might be a lengthy interview.
Vandeven was kind enough to indulge this interrogation, and that is appreciated. Later this month, Sound of Liberation will begin a series of all-dayer events — there are more to come — scattered throughout this year in Germany. The first two announced were the SOL Sonic Ride in Cologne, the SOL Psych Out in Karlsruhe, and for June, already a second Sonic Ride has been announced in Wiesbaden. The lineups of course pull from Sound of Liberation‘s roster of talent: Colour Haze, 1000mods, Slomosa, Greenleaf, Valley of the Sun, King Buffalo, Brant Bjork, Gnome, Daevar, Daily Thompson, Kant, Earth Tongue and Lucid Void spread across the three-so-far lineups. Posters are included along with the Q&A that follows here.
I guess there’s a fair amount of assumption here that you know who Matte is and what he does, but for over 20 years he’s played bass in My Sleeping Karma — and was in The Great Escape before that — and headed up one of underground Europe’s broadest-reaching and most-impactful booking concerns. He is, in short, a professional, and someone who has helped shape heavy rock and the various associated microgenres as they are today. We’ve spoken before, so I wouldn’t say I was nervous to talk to him, exactly — no more so than when talking to humans at all — but this is somebody whose work and passion I deeply respect. It was great to catch up with him.
Congrats to SOL on 20 years, I can’t friggin’ wait to see My Sleeping Karma at Freak Valley this June, thanks to Matte for taking the time and thanks to you for reading. Q&A has been edited for clarity. Please enjoy:

Happy 20th! I know, of course, the 15th anniversary celebration was a giant wreck because covid, although eventually it all worked out right. But I assume you’re hoping for a much smoother go on the SOL Sonic Rides. Tell me about 20 years of Sound of Liberation, what that means for you.
First of all, JJ, thanks for your time. It’s a pleasure to meet you here, and hopefully, soon in person. 20 years of Sound of Liberation. What can I say? Like everybody said, like, “Whoops. That was 20 years ago already?” Time’s passing by so quickly. So yeah. Hey, you named it. We wanted to celebrate the 15th. It was crashed by the covid pandemic, and we are just being thankful we have the chance to hopefully celebrate throughout the year on all our events, and see all the lovely people again which supported us over the last 20 years. At the moment, it’s just a feeling of being thankful to still do what what we are doing. And continuing hopefully, another 20 years of doing what we love.
I think it says something that the way you’re celebrating your 20th anniversary is basically by making a bunch more work for yourself. You have the Sonic Rides in March and in June. Is there more coming?
Yeah. See, here’s the thing. We’re doing quite a bunch of events throughout the years, with Keep it Low Festival, and also there’s Desertfest Berlin, and Up in Smoke in Switzerland. But, it turns out that we still have 40-50 bands on our booking roster, and we are trying to get as many as possible of them invited to events, and it turned out that the March period was fine for a few bands which are touring like Greenleaf around.
And yeah, Cologne was the easy city to reach, and we got the chance to gather the first 10 bands there, and in the summer period the King Buffalo dudes are around. Brother Brant Bjork is around, and so on. So we we added just another one in a beautiful location.
And we are not planning another three or four more, because the fall season is already busy with almost a festival every October weekend. So yeah, I think that’s fine. But let’s see how it goes. You know, we are not always planning things from a very, very long stretch. Sometimes it turns out that you have a bunch of bands around on the same weekend or the same date because of touring, and if we can create a small event out of it, why not?
I imagine over the course of 20 years you’ve seen a lot of venues come and go, a lot of bands come and go, but I imagine between SOL staff, bands and venues, you’ve built significant relationships along the way. Can you talk to me about developing those relationships and how that has let you extend your reach with Sound of Liberation?
I mean in 20 years like you said so many paths are crossing again, and when I think really back to the pioneer pioneer days, or whatever you want to call it, I have to name Colour Haze from Munich because Stefan is, in let’s say this underground music niche stoner heavy rock for so long as well with his Elektrohasch label and Colour Haze celebrating 30 years this year. I think Stefan with his label, and also starting to do first let’s say heavy rock happenings, back then.
In the year 2000, Swamp Room Mania or whatever it was called back then in Munich, there was already built a strong relationship. I was able to book then the first Colour Haze tours, and they are still on our roster now, and they are hitting the road [this] Friday on a bigger European tour.
That was 20 years ago, when we started searching for places where small German underground bands could find a spot to rock, and sometimes it was in just in side rooms of of bars, and you needed to wait until the sports event on the TV is over and you have built and even brought your own P.A. in the in the van. And then there was like eight drunken people there and listening to music they didn’t understand, so no.
That’s why I want to name color is because among many other bands. It’s a close relationship with Stefan for many years and understood how difficult it was for him also to press vinyls and release music only a bunch of people seem interested in so.
So you go from putting Colour in the side room at the bar to, with the festivals you mentioned, having a bit of an empire going. As you said, it’s every October weekend there’s a SOL-affiliated festival.
It’s every weekend in October, because you have up and you have Up in Smoke. You have Keep it Low.
There’s Desertfest Belgium.
Lazy Bones in Hamburg. Yeah, to look it, it sounds like an empire and building up something big. But I really have to say, like, it came organically, if we wanna use that word, and it would have not been possible without a great team I have behind me, and also the partnerships we are in, because honestly, I was not running around and calling throughout Germany to see who was interested to do a stoner rock festival in their venues, it’s the venues we are working with.
Or it’s the promoters, like in Switzerland. They have been in the market for a long time, and they were interested. Once we came around with club shows, they said, “Wow, this was big fun. Can we have more of those, or is there not a chance to do a one-day event or something like this?” So it was not only pushed by Sound of Liberation, or by me saying “I have something, and let’s make something big out of it.” We started all these events super small. I think, on the first Up in Smoke Festivals, maybe 300, 400 people in that 1,000 people room.
Keep it Low was for many years in the beloved place of the Feierwerk in Munich, which is more, two rooms with 400-450 capacity. But it was growing in the last couple of years so much that we needed for production terms, also to use the bigger venue in Munich, so what I want to say is,
we started something small as a really, yeah, an event for us, without the meaning of a financial profit, or like a building up something super big. It was more like it came over the years. And all these events are now like 10 years old already. So it’s nice that people still coming and are interested in. And yeah.
For example, Lazy Bones is a nice thing, because we we started it right after the pandemic as a two-day event in the center of Hamburg in summertime. And we were thinking like, “Wow, for sure, after the pandemic everybody wants to see live concerts.” In the end we had a massive lineup really like with I don’t know, Witch and King Buffalo, and 1000mods and Colour Haze and My Sleeping Karma and and and… and I think we had one day 250, and one day 280 people only for a lineup, which would probably draw 1,000 people. The people who were there like they were saying, “We are ashamed for Hamburg, we don’t know what’s happened.” And we said, “Okay, let’s give it another try.” I mean, it’s Hamburg. It’s a great city. And a year later it was working out much better already.
In the last 20 years, internet word of mouth, and now algorithms, have changed the way people encounter new music. How has that affected what you do? So much of promotion happens online now.
Yeah, I mean, you know it, JJ, and the people listening to our words now, they know it as well how fast the wheel is turning nowadays, and I would be lying if I would say, we don’t push the social medias. Of course we need to push it, because yeah, it’s part of the business now, like on every other business as well. You need to have a social media presence to be noticed.
Maybe the good thing is, when we started there wasn’t so much chance of social media and we were used to like sending our own posters and sending our own flyers, and hanging the posters in our favorite bars and rock bars and venues, and spreading the flyers in the street. So we also understood how.
Let’s say, how is it called mouth to mouth propaganda works. And yeah. So I think that’s good and helps to still have this knowledge. And yeah, to have built up a scene already before all the say social media took it mostly over nowadays. But we are still getting normal emails.
So also, when you are standing at the merch booth and talk with fans, especially a bit older ones, they are saying, like, you know, “we don’t use the Instagram. Send us an email or a newsletter. We prefer that because we are not Instagramers, Facebookers, Tiktokers, or whatever.”
In general terms for Sound of Liberation, what are you looking for from a band? And I don’t necessarily mean something specific, sound-wise. But is there something in terms of attitude or work ethic, or even musically, that lets someone stand out?
That’s a good question. That’s the that’s the tricky one, I mean. There’s so much good music out there, for millions of fans. Only a few like getting the attention, and many more deserve the attention as well.
Sometimes it’s not only in the music. Sometimes it’s not only in the attitude of the band, it’s maybe a mix of both. But let’s take an example: Slomosa, which are pretty much kicking off worldwide in the heavy rock scene. We discovered the band on a Spotify playlist. We loved this, let’s say, ‘hit record’ debut record. And I think that’s maybe very first point, they had a strong, very first record, like, let’s say, with hits on it, or music that catches you right away where I think like, “oh, what is this band? Wow! That that song sticks in my head I have to check, is there more?” And then finding out that the band is willing to put a lot of effort in their music and also in touring. So we started to bring them on live concert, and they develop themselves from a very good live band already into a live machine like super-good, super-good live playing band. So all in all, the complete package worked pretty great — like the album was good, they were on the road when they were playing shows. It went very fast that they were able to take the next steps. Of course we could help with booking expertise and putting them maybe on the right spots on festivals or support tours.
But I just wanted to name Slomosa, because it was very quick and was a band which came out of nothing, so to say, so to sum it up, every band has the chance. There was no demo center on. There was no management which pushed, or music industry which pushed and said, “this is the next big thing.” There were some good songs on Spotify. Maybe on the right playlist. So I don’t know how that worked, and in the end it led to a very fast progression of the band.
Slomosa kind of came out of the gate ready though. With most bands, they gel over the first few records, depending on the band. Some get there, some don’t. What do you do with a band who destroys live and the record’s not there? How involved with your bands can you get? Or have you gotten?
It really depends from band to band. If we are asked for our opinion, we give the opinion, but we don’t point out and say like, “Hey, you should do this.” It’s art, and everybody has their own perspective on it. But now, in viewing it, sometimes we wish some bands would maybe ask a little bit more around what they could do better in terms of maybe songwriting or structures, getting some more advices, not from me, but maybe in general, before they put out a release to get the maximum out of it. But yeah, it really depends from band to band. I mean only a few bands in our genre are putting really all their efforts or dedicating their life just to this band, to reach the next steps very fast, to be maybe even be able to live from the music. That’s already difficult.
Let’s say we are working with a lot of semi-professional bands in our genre. The people have normal day jobs and have music as a hobby and the free time they have, they’re using it for touring or recording. And yeah. So the advice we could give is really individual to the artist, on the path they are choosing for their music. But If the right demo comes, and the right attitude is there and the band really wants it, I think, as a booking agency in our genre, of course, we are able to help and to get the band faster on some bigger stages, because that’s still the most important. The more people you can have in front of stage, and you can convince about your music, the better the chance to step up the ladder a bit a bit faster.
You mentioned King Buffalo before. That’s an established band you’re bringing in. Obviously, that’s a different process from plucking a new band starting out. What are some of the considerations there?
King Buffalo is also a good example. They are a super-hardworking band. It’s work like it’s really a machine, like so much output they had during the pandemic and after and all with great quality. And that’s what I meant before, like these are guys who, like dedicated their lives to their band and they love touring. And all the time you see the list of touring in the States over here in in Europe, you think like so wow! Are they having a home, or are they just on the road?
King Buffalo has reached let’s say, a certain level, where it’s easier for us to book, because they have proved they are super live band, and they have the great albums, and they have a good following. So they are getting the chance to go bigger and bigger in the in the venues. Now they can play some bigger club shows already in in bigger venues, which is very, very good for the time the band is around, because they are still a still a young band, and they have a lot more to come for them if they continue like that. I have no doubt on that.
Is it harder now for a US Band to go to Europe, or for a European band to go to the US?
I think it’s still more difficult for a European band to go to the US. With all the visas you need and a bit harder conditions than we have over here in Europe. I think it’s still easy to plan your European tour, and of course you need some paperwork, but not that much. And, as you know, JJ, we have a there’s a good infrastructure also out here with van rentals and backlines and the driving distances are shorter, maybe. The hospitality is a bit better. No offense.
I get it. You might get a meal or a place to stay in Europe. You probably don’t get a meal in the US. Yes.
It’s still easier for the bands from the US touring in Europe than vice versa.
No, my country totally hates culture. It’s an ironic part of our culture. To shift gears entirely, My Sleeping Karma in December came back to the stage for your first shows since Steffen passed, and I cannot imagine how emotional this was for you. This first gig in particular. Can you talk a little bit about bringing the band back and what that’s been like? You have a busy year coming up at this point, and I keep seeing more added.
My Sleeping Karma is also 20 years old, so it’s big part of our lives. Seppi, Norman, and me, who are still around and able to now continue again with My Sleeping Karma, which was a very tough and very emotional and very sensitive decision. We have been the same lineup for more than 20 years. The band is years 20 old, but we had other projects before we were playing together. And we were really questioning and doubting if if we can continue with Sleeping Karma or bring this back again with a with a live show.
It took a while, and at one point our light engineer, who was traveling with us for years, Andre came up and asked Seppi and me if it’s possible just to jam just for like the sake of a jam. And maybe he had the feeling these guys need to have guitars in the hand again, and need to just be together again, to be able to even think about continuing, because we had not met up for a year. Nobody wanted to go in in the rehearsal room. Nobody wanted to, I don’t know, even talk about the band and so we did this jam and it felt good. Maybe it just felt good to hear the sound again of our band, or feel the vibe of the of the band members like just doing their thing what we have started long time ago.
And so we left on these meetings a bit with an open end and said, “Hey, okay, if the time fits like we jam another time and a few months later there was the time again to meet up and to jam. And Andre came prepared like with five songs really he worked on. He didn’t really say anything about it and we played Sleeping Karma songs, and it sounded alright.
Over the next couple of weeks and months, it developed more and more the idea of like, “Hey! What do you think? Should we do it again? How is it feeling for you like a lot of forward and backward until we…” and I, I really have to say, the fans and friends, and also the families, were a big, big part of this, encouraging us saying, like, “Hey guys, please, life needs to go on. And you guys are there and don’t stop making music. Please go on with that band. It means a lot to us.” And we got so many messages and so much feedback and we decided to continue with Sleeping Karma.
And we really did not know until that first concert in Munich on Colour Haze’s 30th birthday, two days before our hometown show in Aschaffenburg, if it would work, how it would feel the first time on stage in front of people. And then also with bands we’ve known for a long time, it all felt super alright, I think. Very emotional concerts, but also with some magic in which I cannot describe.
Everybody who plays in bands and knows I’m not talking about the groove or the flow like it was more This grown energy, which was there again, and not just created by the moment but created from us the band members over years, and so half of our life and everything was somehow in, and it was somehow clear: We are doing the right thing. It was clear not because people gave a lot of applause or wanted encores. But it was there the full moment, the full thing, why we started the band. And yeah, I hope we have Steffen’s blessing for that to continue.
I would imagine so. I have never seen My Sleeping Karma, and I don’t know if you know this, but I’ve been a fan of your band since your first record. So 20 years.
Yeah, we never made it to the US.
No, no, it’s not on you. It’s on me. But I this year is the year I’m lined up to see the band. Freak Valley’s on the calendar. I have been looking forward to it since that announcement.
We’re looking forward to that show as well at Freak Valley Festival. It’s always also like a homecoming. Good people there and it will hopefully be a great night, another emotional one.
There will be more concerts before this. I don’t know the number, but it’s not really a lot. We are not able to go on bigger tours now, or we didn’t want them. It’s like more still, finding our place again.
One more topic jump. The label. You gotta tell me about SOL Records. I feel like, okay, SOL Records happens a few years ago. I get the email about it. My response was like, “Well, yeah, duh.”
In 2005 we started Sound of Liberation and a few months later I had also founded that record label but never had the time to take care of it. At that time I was the one man army and had too much going on with the booking agency.
But yeah SOL Records also grew organically. My beloved word, organically growing, haha. But it is really like that. And so pretty much what happened, the pandemic came — no more live music. Everything crashed down, no more touring. We were sitting on a bunch of merch like already produced for festivals, already produced for touring bands. A lot of leftover back then from years of music business. So we said, “Okay, only chance. We can still go on doing things we love. Let’s build up a webshop.” With the help of our former employee “Stef” we launched the shop and afterwards we were thinking , “Why are we not releasing at least music we like without a small without, like, you know, searching for the biggest bands right away, and starting just with people we know, and friends and underground music. Our employee, Jakob (26 years old) is taking care of the label now.
He was working in a record store, and he came to our team and he said, “Hey, I really I really love this all. I love the bands. I love the sound. If I would have the chance to work a few hours on the mail order, and maybe on the label at one day.” And so we said like, “Hey, so why not? If we have somebody who’s like really focused and dedicated on this. Who wants to do it.” More or less, it’s in Jakob’s hands.
So then one thing came to another, we had the chance to re-release Trails & Passes from Greenleaf. You know the rights were free, and they gave us the chance, and also Monkey3’s 39 Laps record. And then we did our own releases. And all of a sudden I don’t know what one and a half years we had six or seven releases. We didn’t understand how fast that goes. We were a bit lucky also with pressing plants, because, as you remember, in the pandemic it was a wreck. Six to nine months until you were able to get a pressing plant or the finished product. And we had good luck. We were able to get four releases or something right after the pandemic.
And now same here with the label. We are not pushing it hard heart and signing bands, and, you know, like releases releases releases. It’s more like, Hey, what do we have the capacity for? Which music fits us right? And yeah, then. So no big business plans behind. No, not the not going for the giant corporate. Just needed to be done.
My favorite thing about it is it’s young bands. You mentioned the reissues and stuff, too, but you’re signing new bands.
Like guys from Ruff Majik. You have heard their music, or maybe you’re familiar with the band from South Africa, loving totally what they are. Yeah, and those guys have so much energy and put so much effort in and reached out more or less for help. And we booked the tour. So we made a plan and said, like, “Hey, why aren’t we are not doing things the right way? Let’s have a release ready next time when you are touring.”
Because do you remember how often that goes like, hey, we go into album-release tour, and then all of a sudden, sorry, album is delayed for two or three months, so we are trying to avoid that a little bit with not a business plan, but with a better structure and long-term planning. And I think that also helps a lot.
I think that’s also super important for young bands to have a bit of a timeline. I know it’s super difficult to think “Oh, we are now in February, what are we doing [next] winter? But every bigger or known band already knows what they are doing [next] winter, either recording or touring. So that’s also a big part of the growing process of a band, having a good plan structure and a good timeline for themselves to understand, “these are our goals we want to reach,” and also transporting these ideas to their partners or business partners, like record labels and booking agencies in order to get the maximum out of it.
Because, how often has the promo for the record come after once the tour was done, band was back at home? “So, hey, I just discovered this band. Let’s see when they are coming on tour. Oh, shit! They were here two months ago.”
If we can help with that with our expertise, that also helps. But back to the point. Still, we love what we are doing, and we are still infected by sound. And the music is the most important. And if a demo hits us or a band hits us, and then we yeah, then it’s not easy to say, no, we want to help because we love the album so much, or like the band, so much. So. Yeah.
So we released the Ruff Majik record, and what I like about it is it was not no more the typical, let’s say, Black Sabbath stoner rock, like there was so much different kind of rock music in, and so much freshness in that record that we decided like, “Hey, we wanna we want to release that one.” Not only we want to help Johni [Holiday] because they were in the EU touring, and nobody gets rich selling vinyls or CDs.
And I guess the touring helps them a lot, you know, being around a lot seeing other bands sharing the stages. Playing a lot live is the most important. I know it’s a difficult thing, “How do we get on the stage?” It’s always the same thing. Do you have a good demo? But you have no chance to play live. Difficult. It stays difficult, but there’s a big chance out now with the social media and the web like to gain new fans, friends, clients, however, you want to call it like it was never, maybe never so hard, but also never so easy to be recognized like this.
