Portland, Oregon's Rotting Sky has spent over a decade building suffocating soundscapes where funeral doom's glacial pace meets the bleak atmospherics of black metal and ambient drone. Their music is slow, cavernous, and oppressive — less concerned with riffs than with the weight of sustained decay.

Los Angeles outfit Rowsdower, active since 2011, occupies the slow and swampy intersection of sludge, stoner, and doom metal — thick riffs, deliberate tempos, and the kind of hazy, heavy atmosphere that the LA underground has cultivated for decades. Their sound favors groove and weight over speed.

Orlando's Royal Graves fuse the brooding weight of doom and sludge with post-metal's cinematic expansiveness, crafting music that moves between crushing low-end heaviness and more spacious, emotionally textured passages. Formed in 2017, they're a thoughtful presence in Florida's heavier underground.

Boston's Rozamov, formed in 2015, blend the psychedelic haze of stoner metal with the slow, oppressive roll of doom, building long-form songs that burn low and heavy without sacrificing atmosphere for riff worship. They are a reliable fixture in the northeastern heavy underground.

Georgia's Rugburn occupies a punishing industrial-sludge space where drone, doom, and mechanized noise grind against each other under massive low-end pressure — a sound less interested in conventional song structure than in the slow accumulation of sonic damage. Formed in 2021, they are among the more abrasive presences in the state's underground.

Boston's Rula Bula occupy the slow, suffocating space between doom and traditional heavy metal, pairing monolithic riffs with the kind of brooding weight that's been a Boston underground fixture since 2014.

San Marcos outfit Ruminations blend death metal ferocity with the glacial, suffocating weight of doom, crafting death-doom that leans into oppressive atmosphere and crushing tempo shifts since 2020.

Out of Great Falls, Montana, Runecaller traffic in slow-burning stoner doom, fusing the fuzz-heavy haze of stoner rock with the lumbering dread of doom metal in one of the state's more isolated metal scenes since 2022.
