Eugene, Oregon's Gamma Knife wield an unlikely but effective fusion of stoner metal's slow churn and death metal's gutting aggression. Active since 2011, they're one of the longer-running acts in the Pacific Northwest's underground and have honed that collision into something genuinely their own.

A fresh North Carolina entry in the heavy metal/hard rock tradition, Gamma Razor formed in 2023 with a sharp-edged, no-frills approach to classic metal songwriting. Still building their catalog, they show early promise in a state with a quietly strong metal scene.

Arlington thrash metal. Ferocious late-80s Texas thrash with technical chops.

Providence, Rhode Island's Gamohra splice melodic death metal's harmonic intelligence into a thrash metal framework built for velocity and brutality. Since 2015, they've been one of the more technically ambitious acts working out of the New England underground.

Crushing Death Metal / Grindcore from Houston.

Houston's Ganglion combine death metal's visceral weight with grindcore's frantic tempo and brevity, carving out a space in one of Texas's most active extreme metal cities. Since 2013, they've been a caustic fixture in the Houston underground.

New Jersey's Gangora have been grinding out a caustic death/grind hybrid from East Brunswick since 2020, leaning into the genre's most abrasive tendencies with clear enthusiasm. Short, sharp, and ugly in all the right ways.

New Jersey's Gangr emerged in 2023 with a stark black metal approach that favors atmosphere and malevolence over accessibility. Still early in their existence, they carry the project-style intensity common to the current US black metal underground.

Kingsport, Tennessee's Gangrene Womb play goregrind with the kind of gut-level nastiness that the subgenre demands — fast, foul, and completely committed to its own sickness. Formed in 2022, they bring Appalachian grime to one of metal's most extreme sonic corners.
