Lubbock's Heavens Final War have been fusing hardcore's rage with thrash metal's technical attack since 2015, creating a confrontational sound that fits right in with West Texas's no-nonsense ethos. Their crossover energy is blunt and unapologetic.

Camden, New Jersey's Heavy Coughin specialize in the slower, foggier end of stoner and doom metal — riffs thick as smog rolling in off the Delaware River, dragged to a crawl and left to marinate. They've been perfecting this low-tempo heaviness since 2016.

Brooklyn's Heavy Reign blend neoclassical metal's formal rigor with progressive metal's exploratory tendencies, a pairing that yields music of unusual compositional ambition from this 2022 New York City act. They bring a concert hall sensibility to music built on distorted guitars and dynamics.

Heavy//Hitter emerged from Orlando's underground in 2017 with a mission to crush the norms of mainstream metalcore through their chaotic blend of deathcore, beatdown, and sludge. Vocalist Austin Hayes leads the assault through devastating breakdowns and guttural vocals on releases like 'HATE MANIFEST' and 'Moments of Misery.' Their signing to Blue Grape Music in 2024 brought wider attention to a band that had already been terrorizing Florida's heavy music scene for years.

Milwaukee's Hecatomb emerged in 2020 channeling melodic death metal's twin-guitar attack and structural sweep into well-crafted material that sits comfortably within the Scandinavian-influenced wing of the American death metal tradition. Their approach favors melody without ever losing the genre's essential brutality.

Richmond's Hectic Polarity navigate the disorienting space between industrial metal's mechanical pulse and sludge metal's tar-thick riffing, producing music that's both mechanically precise and organically crushing. Formed in 2020, they represent a relatively uncommon pairing in the American underground.

Portland, Oregon's Hectic Shock have been thrashing with blunt efficiency since 2016, drawing on the genre's classic mid-80s blueprint while operating in one of the country's most fertile underground metal scenes. Their music is direct, headlong, and disinterested in revision.

Milwaukee's Hedda have been weaving progressive and power metal together since 2006, combining the latter's melodic lift with the structural ambition of the former into an approach that prioritizes both feeling and technical execution. They're one of the Midwest's more durable prog-power acts.

Providence's Heel drag death metal's grim cadence through the mire of sludge, producing something heavier and more hostile than either genre accomplishes alone. Active since 2017, they're a natural fit in Rhode Island's gritty underground, where the two scenes have long overlapped.
