Grinding Sludge Metal / Hardcore from Austin.

Portland, Oregon black/death/grind outfit formed in 2019, drawing on the Pacific Northwest's thriving extreme underground to deliver short, vicious assaults that refuse to settle neatly into any one extreme subgenre.

Seattle grindcore act formed in 2018, adding to the city's historically robust underground scene with the blastbeat density and throat-scraping vocal attacks that define the genre's most uncompromising practitioners.

Milwaukee death metal and metalcore hybrid active since 2007, a long-running fixture of the Wisconsin underground combining the blunt-force trauma of death metal with metalcore's structural aggression.

Chicago death metal and grindcore band formed in 2015, operating within the city's deep-rooted tradition of extreme music and drawing on both genres' shared appetite for speed, brutality, and lyrical grotesquerie.

American brutal death metal and goregrind project formed in 2020, doubling down on the most viscerally extreme end of the death metal spectrum with hyper-blasted tempos, guttural vocal extremity, and gore-fixated imagery drawn from the goregrind tradition.

Cleveland's Putrefy deal in a corroded hybrid of black and death metal, leaning into atmosphere as much as brutality with a raw, caustic sound that reflects the rust-belt underground. Active since 2014, they occupy a grimy middle ground where blastbeats collide with dissonant, suffocating riffcraft.

A very recent entry from Kingsport, Tennessee, Putrescent Knight plays raw black metal in the most uncompromising sense — primitive production, icy riffs, and a one-man or small-band aesthetic that prioritizes atmosphere over polish. Formed in 2024, they are among the newest voices in the American raw black metal underground.

Baltimore goregrind project Putricine launched in 2023 and wastes no time on formality, delivering short blasts of splatter-obsessed grind that fit neatly into the city's long tradition of extreme underground acts. Their sound is rooted in the classic goregrind template — churning low-tuned guitars, blast drums, and horror-pathology vocal delivery.
