Washington state's GLA operate in the most unfiltered and deliberately lo-fi end of raw black metal, stripping the genre down to static, spite, and atmosphere. A 2022 project for those who want their black metal as abrasive as possible.

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.

Portland, Oregon's Glacier revive the classic traditions of heavy and power metal with a reverence for melody, soaring vocals, and anthemic songwriting that feels earnest rather than nostalgic. Active since 2013, they're a bright light in the Pacific Northwest's heavier underground.

Blurring the line between arena-ready grit and heavy metal muscle, Gladiator channels both the swagger of grunge and the blunt force of classic metal into something that sounds worn-in and battle-tested. They've been at it since 2010 with no signs of laying down the sword.

Named after the short sword of the Roman legionary, Atlanta's Gladius wields traditional heavy metal like an instrument of precision — focused, punishing, and rooted in the old ways. Since 2011 they've kept the Southern underground stocked with pure steel.
