Crawling out of rural Michigan with the weight of ancient stone, Mammoth Lord deal in crushing sludge-doom built on glacial riffs and suffocating low end. Formed in 2020, the band channels the bleakest traditions of both genres into something genuinely oppressive.

Heavy psych-doom from San Antonio.

Los Angeles' Mange operate at a grim crossroads of doom, sludge, and grindcore — a combination that sounds exactly as ugly and confrontational as it should. Since 2015 the band has weaponized tempo contrast, lurching between suffocating crawls and explosive blasts.

Gray Court, South Carolina's Manticore occupy the slow and heavy space between doom and groove metal, letting mammoth riffs dictate the pace rather than any desire for speed. Since 2019 the band has leaned into midtempo punishment as a core philosophy.

Massive Doom Metal from San Antonio.

Portland's Masonic Weird have inhabited the heavy, hazy space between doom metal and psychedelic rock since 2011, letting their riffs breathe at whatever tempo they demand. Their sound is built for volume and deliberate repetition.

Drawing on the crushing elevation of their Colorado Springs home, Matterhorn plays sludge and doom metal that sounds like altitude sickness made audible. Since 2019, their slow, suffocating riffs have made them a standout in a Mountain West scene not typically known for either style.

Denver's Mead Thief blend heavy doom with the muscle of classic heavy metal, evoking mile-high altitude and long, barren stretches of highway in equal measure. Since forming in 2020, the band has leaned into slow, crushing riffs anchored by a traditional songwriting sensibility that keeps the hooks in reach.

Tulsa's Medicine Horse emerged in 2023 at the intersection of Southern metal, sludge, and doom — a fitting combination for Oklahoma's red-dirt expanse and oil-field grimness. Their sound is slow and swamp-thick, dragging humid riffs through the kind of landscape that breeds spiritual weight.
