Los Angeles' Deimos have been working a progressive groove/thrash metal hybrid since 2000, pulling from the rhythmic muscle of groove metal and the intellectual ambition of progressive rock while keeping the aggression of thrash firmly in the center. The LA underground gave them room to develop a dense, layered sound built for listeners who demand both technicality and physical impact.

Toms River, New Jersey's Delirium Tremens have been playing thrash metal since 1999, named after the violent symptoms of alcohol withdrawal — a suitably unhinged reference for a band with decades of riff-driven aggression behind them. Their Bandcamp handle, fuckposersfucktrends, is a statement of intent that has defined their approach for over two decades.

Madison, Wisconsin's Demento have been at it since 2003, a longevity that speaks to a genuine commitment to heavy and groove metal in a city better known for indie and experimental music. Their groove-driven attack is built on thick mid-tempo riffs and a rhythmic confidence that only comes from years of grinding on the road.

Pittsburgh's Deminion have been forging groove and thrash metal since 1998 — one of the longer-running bands in Pennsylvania's underground, with the battle-tested tightness to show for it. Steel City's industrial legacy seems embedded in their sound: heavy, mechanical, relentless.

Atlanta's Demitri arrived in 2023 with a groove and thrash metal approach suited to a city that has always rewarded heavy riffs with a rhythmic backbone. Young and sharp, they channel the thrash/groove hybrid that defined much of the 1990s extreme metal landscape but give it a distinctly Southern swagger.

Santa Maria, California's Democide bridge melody and brutality with a melodic death metal approach that refuses to sand down the rough edges. Since 2016 they've been crafting riff-driven compositions where harmonized leads collide with aggressive rhythmic passages and growled vocals.

Out of Dallas since 2018, Depth-Charge deal in the kind of groove metal that hits like a sledgehammer wrapped in Southern heat. Their Southern metal leanings give their thick, mid-paced riffs a distinctly Texan swagger, landing somewhere between bulldozing groove and swampy heaviness.

Louisville, Kentucky's Descention have developed a distinctive hybrid since 2010, layering death metal aggression over the churning, down-tuned foundation of groove and sludge metal. The combination draws on Louisville's well-established sludge traditions while pushing into heavier, more abrasive territory.

Woodstock, Connecticut's Desiderium have been working the thrash and groove metal intersection since 2011, delivering driving, kinetic riffwork that draws from both the technical precision of thrash and the body-moving punch of groove. The rural Connecticut setting gives their heaviness a certain unglamorous directness.
