Madison, Wisconsin's Decarabia inhabits the slow-motion apocalypse of sludge, drone, and doom metal, building suffocating walls of low-end distortion since 2016. A different beast entirely from their name-sharing counterparts — heavier and far slower.

Ithaca's Decrement draw from the rich upstate New York heavy music tradition, weaving post-metal's expansive textures together with sludge's grinding heaviness and doom's glacial pace. Since 2018, they've built songs that collapse under their own weight — beautifully.

Cincinnati's Dedwurm twist progressive ambition into the ugliest corners of sludge and death metal, building crawling, labyrinthine structures that collapse in on themselves.

San Diego sludge outfit Deep Sea Thunder Beast drag listeners down into the murk with mammoth, distortion-drenched riffs that move like tectonic plates — slow, enormous, and impossible to ignore.

Los Angeles sludge/doom duo Deep Tomb, formed in 2020, specialize in suffocating, tar-thick riffs that evoke burial — slow, cavernous, and relentlessly bleak.

Denver's Deer Creek have been pulling from the mile-high city's well of sludge, doom, and stoner heaviness since 2006, crafting records that move slow and hit hard.

Portland, Oregon's Defiant Body emerged in 2024 at the heaviest end of sludge and doom, a new entry in a city that has quietly become one of the best homes in the country for slow, crushing metal. Their approach leans into the sludge side of the equation — feedback-laden, emotionally bleak, and physically punishing.

Massachusetts-based Deformed by God emerged in 2020 weaving together black metal's corrosive atmosphere, death metal's brutality, and the thick, dragging weight of sludge into something genuinely unsettling. The convergence of these three styles gives their music an oppressive, suffocating quality — crushing tempos locked beneath waves of caustic noise.

Atlanta's Degradations have covered significant sonic ground since forming in 2017 — beginning with the swampy, heavyset sound of Southern sludge metal before pushing toward the tighter aggression of metalcore. That evolution reflects Atlanta's eclectic underground, where the weight of Southern soil meets the city's appetite for heavier, more urgent sonic textures.

Seattle sludge metal outfit Dehiscent formed in 2021, harnessing the city's damp, overcast atmosphere into the slow, grinding heaviness the subgenre demands. Sludge metal has always thrived in the Pacific Northwest, and Dehiscent fits the mold — thick, downtrodden, and patient in the way that only the heaviest music can afford to be.

New Jersey's DejaGravy have been cooking up a thick stew of sludge and doom since 2013. Built on lumbering riffs and a suffocating low-end, the band wallows in the murk between electric funeral doom and the feedback-saturated grime of Southern-influenced sludge.

Kansas City's Dejecter arrived in 2023 dragging death metal's rotting carcass through the swamp. Their death/sludge hybrid smothers crushing riffs in murk and slow-burning dread, channeling the Kansas City underground's appetite for music that punishes as much as it suffocates.

Austin's DeLizza have been slinging crossover thrash and sludge-soaked metal since 2018, pulling from the Texas capital's eclectically heavy underground. Their sound mashes the short, sharp velocity of crossover punk with the thick, detuned weight of sludge metal — two extremes that share more in common than they might appear.

Out of Franklin, Kentucky, Demeanor have been grinding away since 2013 at a particularly abrasive intersection of grindcore, mathcore, and sludge metal. The rhythmic unpredictability of their mathcore side gives the songs a destabilizing quality that makes the sludge moments hit that much harder.

Out of Antioch, California since 2015, Demonsmoke drag sludge and doom metal through the Bay Area's grimy underbelly, building suffocating walls of distortion laced with a toxic, crawling menace. Their music has the slow-motion fury of sludge's hardcore roots married to doom's infinite, oppressive descent.
