Kalamazoo's Glass God arrived in 2023 at the intersection of heavy metal's visceral punch and progressive metal's structural ambition, constructing songs that feel both grandiose and grounded. A young band with clearly large ideas.

Glass Killing Floor brings a blunt-force metalcore attack from the Louisville underground, pairing serrated riffing with the kind of emotional urgency that metalcore at its best has always traded in. They've been at it since 2019.

Out of Marshalltown, Iowa, Glass Ox forges a strange, compelling hybrid — black metal's cold hostility colliding with heavy metal swagger and a strong punk undercurrent. Since 2020 they've been one of the more ornery acts in the Midwest underground.

From the small town of Somerville, Tennessee, Glass Shrine has quietly cultivated a black metal sound built on atmosphere and sincerity since 2016. There's something devotional in their approach — fragile and fierce in equal measure.

The Oneonta, New York project Glass Skeleton Death March carries a name that promises drama and follows through — blending hard rock muscle with heavy metal bone into music that's both hook-laden and rough around the edges. They've marched forward since 2013.

Genre-defying Austin trio blending post-metal, black metal, sludge, and shoegaze. Signed to Pelagic Records.

Glassjaw emerged from Long Island, New York in 1993 and became one of the most influential post-hardcore bands of their era through sheer sonic ambition and emotional intensity. Daryl Palumbo's frantic vocal delivery and Justin Beck's dense, effects-laden guitar work on 'Everything You Ever Wanted to Know About Silence' and 'Worship and Tribute' pushed post-hardcore into art-rock territory years before it became trendy. Their sporadic release schedule and perfectionist approach only deepened the cult devotion surrounding the band.

Named for the Questing Beast of Arthurian legend — a creature heard but never fully seen — Bloomington, Indiana's Glatisant pursues depressive black metal into abstract, haunted spaces. Their music has the quality of something searching endlessly without resolution.

Taking its name from the Welsh word for rain, Maine's Glaw brings a fittingly damp and hazy energy to stoner metal — loose, heavy, and atmospheric in the way of long gray afternoons. One of the newer acts out of the Pine Tree State underground, formed in 2024.
