Milwaukee's Harlots have spent two decades sharpening the intersection of metalcore and technical death metal into something genuinely punishing. Formed in 2004, they bring the rhythmic punch of the former and the surgical precision of the latter in equal measure.

Chicago's Harm's Way formed in 2006 as a powerviolence side project before evolving into a full-time act rooted in industrial-tinged metalcore. Signing to Metal Blade Records, the band released Posthuman (2018) and Common Suffering (2023), both of which demonstrated a progressive widening of their sonic palette beyond hardcore's usual constraints. Their trajectory from Crossed Out-influenced grind to groove-heavy metalcore has earned them a dedicated following across both punk and metal circles.

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.

Portland's Harness emerged in 2020 pulling death and thrash metal into violent collision, favoring the stripped-down brutality that comes from letting two of metal's most aggressive subgenres do what they do best without decoration.

Oakland's Harness take the groove metal template and sharpen it with thrash's velocity, forming a sound that hits hard from multiple angles. Formed in 2020, their approach is about locking into a groove and then driving it relentlessly forward.

Champaign, Illinois's Harpe steep themselves in death-doom's most morbid traditions — the genre's slow-motion dread rendered in thick, downtuned guitars and a pacing that refuses to rush toward the inevitable. A heavy and deliberate presence since 2020.

Chicago's Harpoon bring the controlled chaos of grindcore to the thrash metal framework, producing music that's fast, violent, and barely contained since 2014. Their sound has the aggression of both genres and the patience of neither.

New Paltz, New York's Harrower have carved a space in post-black metal since 2015, threading atmospheric passages through black metal's abrasive core with a sophistication that feels native to Hudson Valley's thoughtful underground scene. Their music rewards close attention.

Philadelphia's HarrytheHat operate with an eclectic approach to heavy metal, reflecting the city's broad-minded underground tradition since their 2022 formation. Their wide stylistic range speaks to a restless creative energy rather than genre orthodoxy.
