Los Angeles's Grim Death weaponize speed metal's manic energy with thrash's precision and aggression, delivering a tight, stripped-down assault that hits hard and moves fast. Since 2020, they've been one of the more focused purveyors of the classic crossover between those two worlds.

please update this band

Thunderous Groove Metal from Houston.

Houston's Grimlock surfaced in 2024 with a groove metal approach built on thick, mid-paced riffs and a relentless chug — the kind of music that demands movement and doesn't waste time on subtlety. A young band with a clear and punishing purpose.

Mean Heavy / Power / Groove Metal out of Texas.

Fort Worth's Grimoire have been running crossover thrash and classic thrash through a Texas-sized filter since 2011, combining hardcore's directness with metal's riff obsession for a sound that's both technically sharp and relentlessly aggressive.

Knoxville's Grimsteel fuse power metal's melodic ambition with progressive metal's structural complexity, crafting songs that move through dynamic shifts without losing the epic quality that makes the genre soar. Since 2019, they've been one of the more musically ambitious acts to emerge from the Tennessee underground.

Los Angeles's Groamville have been rolling out heavy stoner rock and metal since 2014, favoring down-tuned grooves, fuzzed-out riffs, and a relaxed, head-nodding pace that serves the music's hypnotic power. They're a reliable name in the city's well-populated desert rock underground.

Raleigh's Grohg have spent over a decade wrestling sludge metal and metalcore together into something heavier and more punishing than either genre alone. Since 2012, they've built a reputation on dense, churning performances that don't let up.
