Seattle's Giza build their atmospheric sludge metal with a monolithic patience — slow, layered, and vast in the way their name's ancient stone monuments are vast. Since 2012 they've been constructing music that takes its time to bury you.

Denver's Glacial Tomb work in a devastating three-way collision of black, death, and sludge metal, and the result sounds like being buried under a collapsing mountain in the coldest possible winter. Formed in 2017, they're one of Colorado's most formidable extreme acts.

Portland's Glasghote drags sludge through the mud of doom, coiling feedback and suffocating low-end into something that sounds like the Pacific Northwest itself — wet, gray, and pressing down. Since 2017 they've been one of the city's most punishing underground outfits.

Genre-defying Austin trio blending post-metal, black metal, sludge, and shoegaze. Signed to Pelagic Records.

Reno's Goblin Pussy play sludge metal with the city's characteristic edge — abrasive, feedback-drenched, and resistant to easy categorization. A 2024 newcomer, they've already planted their flag in the muck.

Suffocating Sludge / Doom Metal from Houston.

Tucson's Godhunter fuse the swamp-thick dirge of sludge metal with the caustic aggression of thrash, building walls of sound that feel both pulverizing and politically charged. Since 2011 they've been one of the Southwest's most unrelenting acts.

Morgan City, Louisiana's Golgotha drag sludge metal's tar-heavy riffs through thrash's confrontational aggression, producing something that feels uniquely Southern in its humidity and hostility. Around since 2005 and still grinding.

Kent, Ohio's Goosed have been wallowing in sludge metal's lowest registers since 2018 — mid-tempo riffs like concrete blocks, vocals buried under layers of distortion, and a general sense that things are not going to get better.
