Savage Goregrind from Austin.

Aurora sits in Chicago's orbit, and that industrial midwest grit runs through Melting Rot's aesthetic like a live wire.

Lakeland, Florida's Menstrual Moonshine operate in the overlapping territory between brutal death metal and grindcore where songs are measured in seconds and volume is the primary compositional tool. Formed in 2020, they lean into the Sunshine State's longstanding tradition of extreme metal extremity, weaponizing short-duration brutality and blast beats with the kind of commitment that makes the genre's most outrageous acts genuinely compelling rather than merely provocative. Florida has produced some of the most unhinged death metal in the world, and Menstrual Moonshine approach that lineage with appropriately unhinged results.

Buffalo, New York's Mental Anguish have been grinding since 2018, bringing a relentless grindcore assault to a city with a deep and underappreciated metal history.

They are a Central Coast anomaly and a genuinely punishing listen.

New York's Merciless Mutilation have been grinding through the death/grindcore underground since 2008, delivering punishing short-form brutality that cuts every song to its violent essential core.

Out of Tampa — a city with serious grindcore credibility — Merciless Scum have been delivering caustic blasts of noise and fury since their formation in 2017.
