Set to take place at The Ottobar in Baltimore once again at the tail end of April — 4/20 season, if you’re not the type who gets stoned to do the dishes — the all-dayer Grim Reefer Fest has unveiled its 2025 billing, with Chicago psychedelic texturalists Rezn and D.C. industrialized post-punkers Vosh at the top of the bill, with Temple of the Fuzz Witch coming from Michigan as they continue to spread the word of their own well-received 2024 outing, Apotheosis (review here), Dallas rockers Temptress and the house band Haze Mage taking part, as well as heavy noise rockers Consumer Culture, and Sorge, who are well due for a follow-up to their impressive 2020 debut EP (review here).

Rounding out are Richmond duo Thunderchief, Pennsylvania melo-cult classicists SpellBook and Baltimore’s own Knub, who I’ve never heard of before now but who are killer, opening. Their logo is noise and their sound is too, but throw in some poppier melody and turns out I have some homework to do. I put Knub‘s tracks from their 2023 split with Brain Cave below, in case you also want to dig in. There’s a Black Lung set there too from 2024’s Grim Reefer Fest just for the hell of it — as the fest notes, there’s more on the YouTube Channel — and while I’m dropping dates and links, I’ll note that I was fortunate enough to attend Grim Reefer Fest in 2023 (review here), and if you’re on the fence, I’ll confirm it’s a blast and well run. Maybe that helps? There’s food and such and it’s low-key; an easygoing vibe in which to be variably pummeled by volume.

The announcement from the fest follows here. Keep an eye as some things may change, but it looks like a good time to me as it is. And the poster, as you can see, continues a years-long streak of righteousness from Grim Reefer Fest as well. From socials:

Grim Reefer Fest 2025

We are excited to announce the return of Grim Reefer Fest! Join us once again at the legendary Ottobar in Baltimore, MD for a full day of heavy music, dank vibes, and high spirits! Join us on Saturday April 19th, 2025 as we celebrate the High Holidays with a stacked lineup from start to finish with some of the best bands the scene has to offer! Featuring the heavy psych sounds of Rezn, the mesmerizing Vosh, the heavy hitting Temple of the Fuzz Witch and many more (10 bands total)!

This is the 6th year of Grim Reefer Fest and one of our most ambitious lineups yet! We’re proud of what we’re accomplishing as a DIY grassroots festival. The genres and sounds for this year’s bands range from heavy psych to stoner doom to industrial darkwave to noise rock with so much more in between!
