Wilkes-Barre, Pennsylvania's No Warning Shot have been grinding since 2006, blending grindcore's explosive brevity with death metal's heaviness into something abrasive and unrelenting. Two decades in the Northeastern underground have given them a hardened, no-ceremony approach to extreme music — short, punishing tracks that arrive without announcement and end before there's time to recover.

Washington State's No/Más arrived in 2022 fusing grindcore's commitment to brevity and chaos with the gutting heaviness of death metal — a combination that weaponizes short run times into something genuinely destabilizing. Their name, Spanish for "no more," signals a kind of principled refusal, and their music follows through: dense, fast, and merciless, with nothing wasted and no quarter given.

Unhinged Grindcore from Albuquerque, New Mexico (early); Texas / California / New Mexico (later).

Savage Grindcore from San Antonio.

Phoenix grindcore outfit Nooses have been delivering short, violent bursts of sonic punishment since 2018, channeling the genre's core ethos of maximum aggression in minimum time. Their music is blunt and uncompromising, built from jagged riffs, blast beats, and throat-shredding vocals that leave no room for subtlety. In a city better known for sun and sprawl, they carve out a relentlessly hostile niche.

Nuclear Blaze formed in 2017 with a sound that weaponizes black metal's cold atmosphere against the sheer velocity of grindcore, producing something abrasive and nihilistic in equal measure. The band strips both genres down to their most brutal fundamentals, offering little mercy in the way of melody or breathing room. Their Bandcamp presence marks them as a fixture in the extreme underground.

Ripping Death Metal / Grindcore out of Texas.

Ripping Death Metal / Goregrind from El Paso, Texas (early); Ohio (later).
