One of Maine's most idiosyncratic metal acts, Hallowed Butchery have spent over fifteen years refusing to settle — beginning as a black/grind project and gradually morphing into something incorporating doom, folk, and experimental elements. Based in Kennebec County, their music sounds like it grew out of the woods rather than any rehearsal space.

Phoenix's Halls of Mandos take their name from Tolkien's realm of the dead and build their sound accordingly — doom-laden, post-metal architecture with industrial undercurrents that give the music a cold, machine-like dread. An intriguing young project born in 2023.

New York's Hallux carve out a sludge/doom sound built on weight and repetition — riffs that settle in and refuse to leave, tempos that drag the listener through the muck. Formed in 2018, location unspecified, but the music speaks clearly enough.

Cleveland's Hammr channel the blackened speed metal of the early 1980s with a punk-soaked fury that fits perfectly in a city with a long history of no-bullshit heavy music. Active since 2018 and showing no signs of slowing.

New Jersey's Hand of Weed keep the doom and stoner metal flame lit with fuzzed-out riffs and a smoky, slow-motion heaviness that earns every minute of its runtime. Active since 2015.

Portland's Hands of Thieves cast a wide net across black, death, and doom metal, conjuring something genuinely dark and multifaceted since forming in 2016 in the Pacific Northwest underground.

San Diego's Hanging Garden have cultivated a strain of depressive black metal since 2013 that leans heavily into isolation and despair, letting long, suffocating passages take root in the mind.

Painesville, Ohio's Hangnail have been grinding away since 1998, their thrash and grindcore roots keeping them lean and mean across nearly three decades of relentless, no-frills extremity.

Newly formed in 2025, Farmington, Connecticut's Harmozel deal in doom and heavy metal with a reverence for slow, crushing dynamics. They're early in their existence but already trading in the patient, riff-driven heaviness that defines the doom tradition.
