Portland's Gidrah traffic in the filthiest and most suffocating end of sludge and doom, building walls of corrosive tone that move with the deliberate menace of something enormous and ancient. Their sound is the Pacific Northwest rain rendered in distortion.

Portland, Maine's Gift of Tongues fuse the atmospheric density of post-sludge with the raw violence of death metal, constructing music that feels both hauntingly spacious and crushingly heavy. Their approach since 2013 rewards those willing to sit inside the weight.

Named after the visionary Swiss artist, Columbus, Georgia's Giger pursue a similarly biomechanical aesthetic through sludge and doom metal — music that feels organic and industrial at the same time. Their riffs carry the weight of rusted machinery dragged through tar.

Borrowing their name from a race of astral-plane warriors, Seattle's Githyanki conjure sludge and stoner metal that feels genuinely otherworldly — dense, psychedelic, and displaced from any comfortable reality. Active since 2015, they're a cult act in the Pacific Northwest heavy underground.

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.

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.
