New York's MKDelta blend hardcore sludge and doom into a punishing, slow-grinding sound that leans on suffocating riffs and bleak atmosphere. Formed in 2022, the band describes their music as something that will make you want to quit your job — a fair warning for the faint-hearted.

A long-running post-metal and sludge outfit from Cortland, New York, Monolith have been building slow, crushing soundscapes since 1993, channeling the weight of upstate isolation into feedback-drenched, deliberate riffs.

Brooklyn's Mortals emerged from the sludge and hardcore underground in 2011 before moving toward a heavier, more blackened sound, carving out a distinct space where sludge's oppressive weight meets the cold fury of black metal.

North Babylon, Long Island sludge/stoner duo Moth Eater launched in 2023 with a thick, fuzz-drenched sound that punches above its two-piece configuration — heavy, hypnotic, and rooted in the grimy New York underground.

Brooklyn doom and sludge metal outfit Mountain God have been hauling monumental, slow-moving riff structures through New York City's underground since 2013, bringing an almost devotional weight to music that feels both ancient and urban. Their sound sits at the slow, heavy end of the New York metal spectrum, indebted equally to Cathedral and Eyehategod.

Brooklyn's Mutant Scum drag sludge metal through New York's gutter, mixing the genre's tar-slow heaviness with punk's frantic energy and street-level aggression. Since 2015, they've added a properly filthy strain of noise to a borough overflowing with heavy underground acts.

Brooklyn's Mutoid Man fuse sludge and stoner metal into something swaggering and overpowering — thick, groove-laden riffs married to a rock sensibility that keeps their sound dynamic and weirdly infectious since 2014.
