Named after the visionary Swiss artist, Columbus, Georgia's Giger pursue a similarly biomechanical aesthetic through sludge and doom metal — music that feels organic and industrial at the same time. Their riffs carry the weight of rusted machinery dragged through tar.

Toms River's Giggler pull off an unlikely combination: fusing the grandiosity of power metal with the slow, oppressive crawl of doom. The result is something operatic and crushing in equal measure, a strange and compelling beast from the New Jersey underground.

Simi Valley's Gilted Woods summon a black metal atmosphere rooted in woodland imagery and cold desolation, working in the second-wave tradition with a distinctly California-suburban sense of isolation. Formed in 2015, they find darkness in the sun-baked edges of suburban sprawl.

Portland, Oregon's Gimp attack from 2017 with a blackened thrash approach that's all speed, spite, and stripped-back ferocity. They weld the misanthropic spirit of black metal onto thrash's most violent impulses without ceremony or compromise.

California's Gingivitis take the goregrind tradition literally, pairing death metal's brutality with grindcore's hyper-compressed intensity and a gleefully grotesque aesthetic. Since 2022, they've specialized in punishing short-form attacks on the senses.

New York's Girder build their stoner doom sound like heavy construction — methodical, load-bearing, and made to last. Formed in 2025, they're among the newest entrants to the northeast's already formidable heavy underground.

Lafayette, Louisiana's Girra draw from both black metal's cold fire and doom's glacial tempos, creating music that feels rooted in the murky, swampy darkness of their Gulf Coast home. Formed in 2015, they merge northern grimness with southern rot.

Philadelphia's Girsu — named for an ancient Sumerian city — approach progressive black metal with a conceptual depth that matches the civilizational weight of their inspiration. Since 2021, they've been mapping interior and historical darkness simultaneously.

Sacramento's Girth have been pounding out thick-necked thrash and groove metal since 2005, favoring riffs with mass and swing over flashy technique. They're a blue-collar band in the best sense — no frills, all force.
