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.

Burlington, Vermont's Hellascope deals in the slow, thick intoxication of stoner-doom, letting riffs unfurl with deliberate weight under a haze of fuzz and feedback. Since 2017 they have operated at the intersection of heaviness and hypnosis.

Oakland's Hellbeard have been mining the Oakland sludge tradition since 2010, piling down-tuned misery onto doom's already crushing foundation. Their sound carries the Bay Area's industrial grit embedded in every slow, punishing riff.

Hellish Form push doom to its most suffocating extreme, folding sludge's abrasive texture into funeral doom's glacial pace and near-unbearable weight. Formed in 2020, they embrace desolation as an art form — slow, suffocating, and strangely beautiful.

Hellmask operates in the furthest reaches of funeral doom and ambient metal, crafting recordings since 2017 that feel less like songs and more like long descents into irreversible darkness. Atmosphere is the entire purpose here, and they wield it with unsettling mastery.

Occult blackened death/doom from the Ordo Satanae Imperium collective. Shares members with Nyogthaeblisz and Nexul. Two albums on Iron Bonehead Productions.

Chicago's Helmer blend doom and stoner metal into slow, hazy monoliths since their 2021 formation, drawing as much from the city's post-industrial heaviness as from the fuzz-soaked tradition of the genre. Thick, meditative, and built for long nights.

Carrollton, Georgia's Her Name Is Death emerged in 2025 with a triptych of doom, drone, and sludge that moves like a slow flood — irreversible and all-consuming. One of the newer acts in the Southern heavy underground, their intentions are already unmistakably bleak.

Out of Wichita since 2018, Hess n Hell deal in the bruising overlap between doom's slow grind, groove metal swagger, and classic heavy riffing. Their sound is blunt and earthy, built for low-ceilinged venues and speakers pushed past their limits.

Los Angeles' Hexen bring melodic sophistication and progressive ambition to the thrash template, threading complex arrangements through otherwise hard-hitting material. Their approach reflects the technical tradition of the LA metal scene while reaching toward something more compositionally adventurous.

Salt Lake City's Hibernaut pile sludge, stoner, and doom into a slow-moving mass that seems calibrated to induce a specific kind of narcotic heaviness. Formed in 2023, they occupy the hazy zone where riff weight and psychedelic drift become the same thing.

Franklin, Indiana's Hidden Dagger blend stoner haze and doom weight with groove metal's rhythmic snap, arriving at something simultaneously lumbering and propulsive. Since 2018 they've proven that mid-tempo heaviness can carry as much punch as anything faster.

Oakland's High on Fire are one of the defining forces in American doom and sludge, built on Matt Pike's mythological vision and the kind of riff density that makes everything around it feel thin. Since reforming their presence in the early 2010s, they have remained one of the heaviest and most uncompromising bands on earth.

Philadelphia's High Reeper navigate the border between doom metal and hard rock with the ease of a band that doesn't feel the need to fully commit to either camp. Since 2017, they've written songs built for maximum riff payoff, borrowing from classic rock's instinct for the hook without softening their heaviness.

Melodic death/doom started as a one-man project by Casey Hurd. Signed to Napalm Records. Albums include Order Divine and Shatter And Fall.
