Philadelphia doom outfit Deliriant coalesced in 2022, channeling the city's dense, oppressive atmosphere into slow-burning funeral doom. Operating under the Bandcamp handle deliriantnerve, the band deals in monolithic riffs and a suffocating heaviness that makes room feel smaller the longer the music plays.

Washington state's Deliriant Nerve formed in 2022 at the intersection of grindcore's brevity and death metal's brutality. Sharing a Bandcamp handle with Philadelphia's Deliriant, the band channels the Pacific Northwest's extreme music community into blasts of grinding intensity and raw, punishing velocity.

Born in 2025 somewhere in Southern California, Delirium Shroud weaponize black/thrash metal's most lethal qualities — venomous riffing, feral tempos, and a production aesthetic that sounds like it was recorded in the ruins of something. Their very recent emergence suggests a project still finding its shape, but the black/thrash blueprint is a proven vehicle for pure spite.

Toms River, New Jersey's Delirium Tremens have been playing thrash metal since 1999, named after the violent symptoms of alcohol withdrawal — a suitably unhinged reference for a band with decades of riff-driven aggression behind them. Their Bandcamp handle, fuckposersfucktrends, is a statement of intent that has defined their approach for over two decades.

Los Angeles's Deliverance carry a storied legacy reactivated in 2020, blending speed metal and thrash with industrial elements in the tradition of the band's long history. Operating out of the LA metal scene, the band weaves mechanical menace through the kinetic force of high-octane thrash, a combination that has made them fixtures of the underground for decades across multiple incarnations.

Chicago's Deliverance formed in 2020 in the heavy metal and hard rock tradition, drawing on the city's deep rock roots. Operating from one of the Midwest's great music cities, the band favors the kind of direct, melody-forward heavy metal that has defined the genre since its earliest days.

Queens, New York's Deliverance formed in 2020 with an ambitious musical scope that blends progressive metal's complexity with the raw aggression of power and thrash metal. Hailing from one of New York City's most musically diverse boroughs, the band weaves together layered arrangements and technical ambition without abandoning the genre's essential heaviness.

Austin's DeLizza have been slinging crossover thrash and sludge-soaked metal since 2018, pulling from the Texas capital's eclectically heavy underground. Their sound mashes the short, sharp velocity of crossover punk with the thick, detuned weight of sludge metal — two extremes that share more in common than they might appear.

Augusta, Georgia's Dellamorte emerged in 2022 as a grindcore outfit named after the Italian phrase for death — a fittingly direct name for a band that delivers rapid-fire blasts of noise-soaked intensity. The band draws from the genre's roots in punk and extreme metal, keeping the songs short, loud, and purposefully destructive.
