Minneapolis's Worn Mantle formed in 2022, grafting the corrosive texture of sludge metal onto a blackened death metal framework — a combination that suits the Twin Cities underground's affinity for heavy music that is both abrasive and emotionally oppressive. The band brings a multi-genre brutality to a city with a strong tradition of extreme metal.

Colorado Springs' Worry have been trading in the sludge-hardcore crossover since 2017, building a sound that is slow enough to crush and aggressive enough to pummel. Their music draws on the bleak altitude of the Colorado Front Range, pairing sludge metal's deliberate heaviness with hardcore's blunt-force urgency.

New Bedford, Massachusetts's Wound Man fuse sludge metal's crushing weight with powerviolence's white-knuckle aggression, channeling the post-industrial decay of coastal New England into short, suffocating bursts of noise since 2013. The band's cross-genre approach makes each release feel like a trap door opening beneath you.

San Francisco's Wrack have been hauling sludge and doom through the Bay Area underground since 2016, blending the city's storied tradition of heavy music with slow, corrosive riffs built for endurance rather than speed. Their sound evokes the weight of the fog-laden coastline — dense, unhurried, and unrelenting.

Brooklyn's Wretched Tsar have been dragging sludge and stoner metal through New York's underground since 2016, combining the slow, crushing weight of sludge with the hazy, amplifier-worship side of stoner metal. The result is heavy in both mass and atmosphere, made for dark rooms and loud speakers.

Columbus, Ohio outfit Wurm Sun fuse the crawling weight of doom metal with the abrasive filth of sludge, conjuring a suffocating heaviness that feels born from the industrial grimness of the Midwest. Active since 2022, their sound prioritizes atmosphere and oppressive volume over speed.

Wyoming Young and Strong are a Seattle sludge metal act formed in 2019, channeling the Pacific Northwest's tradition of heavy, feedback-laden music into dragging, punishing dirges. Their name belies the bleakness of their sound, which leans into the oppressive end of the sludge spectrum.

Yautja formed in Nashville, Tennessee in 2010 as a trio — guitarists Shibby Poole, bassist Kayhan Vaziri, and drummer Tyler Coburn — intent on bridging grindcore velocity with sludge metal density, a pairing they pursue without compromise. Their debut Songs of Descent drew critical attention for the conviction of its execution, and The Lurch (2021, Relapse Records), recorded at Steve Albini's Electrical Audio studio in Chicago, offered a more expansive and dynamic take on the same confrontational template. The band has been described as one of the most cohesive practitioners of the grindcore-sludge hybrid.
