Alexandria, Virginia's Gasmask616 pulls from melodic death metal, deathcore, and beyond, treating genre as a suggestion rather than a constraint. Active since 2021, they've built a catalog that moves fluidly across the extreme metal spectrum.

Los Angeles experimental outfit GASP has been pushing at the edges of sludge metal and hardcore since 2009, folding in noise, feedback, and abrasive texture until the genre lines dissolve entirely. Their music is confrontational and unpredictable, shaped by LA's eclectic and uncompromising DIY underground.

Phoenix sludge merchants Gasping have been dragging listeners through tar-thick riffs and caustic misery since 2011. Their sound leans into the suffocating, oppressive end of the genre — slow-burning and relentless.

A brand-new goregrind project from Connecticut, Gastric Fasciitis arrived in 2025 with the kind of clinical-horror fixation and blasting ferocity the genre demands. Short, violent, and deeply unpleasant in the best possible way.

Denver's Gastric Phantasm carve up a nasty intersection of goregrind and death metal, keeping things visceral and churning since their 2021 formation. Equal parts intestinal and infernal.

Chicago's Gastropod blend grindcore's furious brevity with death metal's crushing low-end, building a sound that's both abrasive and rhythmically punishing. Formed in 2023, they're a welcome new entry into the city's brutal underground.

Named for the mythological passage of true dreams, New York's Gate of Horn weave together sludge, stoner, and doom into a hazy, lumbering mass that feels ancient and psychedelic at once. Active since 2014, they remain one of the more atmospheric acts in the tri-state heavy underground.

California crossover outfit Gatecrasher play the kind of thrash-fueled hardcore that belongs on sweaty club floors, tight and frantic with a punk-derived chip on their shoulder. Formed in 2019, they hit hard and keep it short.

Tucson's Gatecreeper have become one of American death metal's most celebrated acts, channeling Swedish buzzsaw tones and suffocating groove into anthemic, punishing albums since 2014. Their rise from the Arizona desert to international stages is one of the genre's great success stories of the last decade.
