Queensbury, New York's Girthquake channel death and thrash metal into a sound that's simultaneously old-school in its riff vocabulary and aggressive in its forward momentum. One of three unrelated bands sharing this name, they hold their own on the strength of pure speed and spite.

Boston's Give Zombies the Vote merge melodic death metal's harmonic sophistication with metalcore's rhythmic aggression and a name that's equal parts political provocation and horror camp. Active since 2012, they make technically ambitious music that never forgets to be fun.

Baton Rouge's Glacial Coffin fuse black metal's cold hostility with death metal's crushing physicality, arriving at a sound that's both frozen and brutal at once. Since 2019, they've been one of Louisiana's most interesting extreme metal entries.

Boston's Glacial Hell combine death metal's heaviness with hardcore's relentless forward aggression, producing music that's fast, confrontational, and brutally efficient. They've been part of the Massachusetts extreme underground since 2017.

Denver's Glacial Tomb work in a devastating three-way collision of black, death, and sludge metal, and the result sounds like being buried under a collapsing mountain in the coldest possible winter. Formed in 2017, they're one of Colorado's most formidable extreme acts.

Newly formed in 2025, Glizzy Gobbler throws the entire brutal death metal playbook at the wall — slam, goregrind, grindcore, and sheer disgusting force — packaged inside a name that refuses to take itself seriously. The music does not share that restraint.

Detroit's Glockmouth launched in 2025 with a deathcore attack as blunt and urban as the city they came from — dense, mechanically brutal, and pointed like a barrel at everything soft. Motor City heaviness filtered through modern extreme metal.

Florida's Gloombringer arrived in 2023 fully committed to the most brutal and anatomically absurd corners of slam — pit-collapsing breakdowns, guttural vocals, and the relentless low-end punishment that defines the genre. They bring gloom in the most literal tonnage sense.

Fleetwood, Pennsylvania's Gloominous Doom is one of the underground's stranger propositions — progressive death and thrash metal with recorded ska influences woven in, making for something genuinely difficult to categorize and harder to ignore. They've been at it since 2015.

Atlanta's Gloomreach pulls death-doom into D-beat territory, pairing the glacial weight of death/doom with a rawer, more punk-informed attack that keeps the music from ever fully settling into complacency. Formed in 2018, they're one of Atlanta's more unpredictable extreme metal acts.

Glencoe, Missouri's Glorious Death has been pushing experimental black and death metal into unpredictable territory since 2014, willing to fracture structure and embrace dissonance in ways that make them stand apart from their more orthodox peers. The name is triumphant; the music is chaos.

New York's Glorious Depravity wears its death metal allegiances without apology — riff-forward, brutal, and unapologetically ugly in the ways that matter. Since 2018 they've been one of the state's reliable purveyors of the form.

Minneapolis death metal outfit Glutton for Punishment have been delivering unrelenting heaviness since 2014. Their approach is blunt and carnivorous, rooted firmly in the old-school tradition of American brutality.

Pennsylvania's Gnargoyles have carved out a grimy niche where crossover thrash collides head-on with death metal ferocity. Their sound is ugly, fast, and unrepentant — part pit fodder, part throat-ripping carnage.

Washington state newcomers Gnashed Gash arrived in 2025 with a death metal identity as confrontational as their name. Unpolished and predatory, they trade in visceral extremity without apology.
