New Jersey-based Sigourney combine the murky, feedback-drenched heaviness of sludge metal with the hazy, loping grooves of stoner metal, crafting a sound that is both oppressive and hypnotic since 2020.

Columbus, Ohio's Sin Nombre — the name meaning "no name" in Spanish — have been marinating in the thick intersection of sludge and stoner metal since 2013. Their Midwestern locale adds a certain grey industrial weight to a sound already defined by heaviness, heat, and deliberate, grinding momentum.

Groton, Connecticut's Singe merge the downtuned murk of sludge metal with groove metal's locked-in rhythmic drive, carving a sound that feels as weathered and industrial as their coastal New England setting. Formed in 2021, the band leans into slow-burning heaviness accented by punishing mid-tempo breakdowns.

New Rochelle, New York's Sinicyst emerged in 2023 fusing the dirty stomp of sludge metal, crossover thrash's hardcore bite, and groove metal's rhythmic punch into an uncompromising hybrid that feels like it was forged somewhere between the Westchester suburbs and downtown Manhattan's rougher-edged clubs. Their willingness to blend three distinct heavy subgenres makes for an unpredictable and abrasive listen.

A sludge metal outfit from Fayetteville, Arkansas, Sinking South have been grinding out slow, heavy, feedback-drenched material since 2014, channeling the swampy weight of Southern sludge into a distinctly Ozark-edged sound.

St. Louis band formed in 2023 that drags death metal into sludge metal's murky, slow-burning territory, resulting in music that is both punishing and dense with atmosphere. As a very new act out of a city with a strong underground metal tradition, they arrive with an already fully-formed sense of the crushing and the heavy.

Orlando, Florida sludge and stoner metal band active since 2010, locking into slow, tar-thick grooves and feedback-laden heaviness with the swampy persistence that Florida's humid underground breeds. Their name alone signals the kind of bleakly humorous, road-worn vibe their music inhabits.

Los Angeles sludge and doom metal band formed in 2017, operating in the long shadow of the city's thriving heavy underground with dense, slow-moving riffs and the kind of suffocating atmosphere that characterizes the best of the West Coast doom scene. The "sixesdoom" Bandcamp tag underscores where their loyalties lie.

Painesville, Ohio sludge metal band formed in 2014 — their name leaves little ambiguity about aesthetic intent, leaning into the devil's number with the unapologetic heaviness of a band committed to grinding noise and oppressive low-end. The Lake Erie industrial belt has produced plenty of mean, ugly heavy music, and SixSixSix fits that lineage.
