Shaolin Death Squad are a theatrical progressive/avant-garde metal band from Denton, Texas, formed around 2001-2002, performing under kung-fu-themed stage personas. Their sound is dynamic prog metal with lead vocalist The White Swan frequently compared to Mike Patton, across releases including Intelligent Design (2006) and a 2024 self-titled record on Soman Records.

Potmos Hetoimos is the long-running one-man progressive sludge/doom project of Baltimore's Matt Matheson, active since 2006. The 2018 album Vox Medusae (Not Music) recast a concept about pornography addiction as a nine-voice Greek drama, weaving saxophone and piano into blackened-hardcore-inflected sludge, with jazz/funk touches. The record was mixed and mastered by Angel Marcloid (Fire-Toolz).

Oxbow were a San Francisco experimental/noise-rock band founded in 1988, built on the partnership of vocalist Eugene S. Robinson and multi-instrumentalist and composer Niko Wenner. Their music blends noise rock, avant-garde jazz, musique concrete and blues into caustic, paranoid soundscapes framed by Robinson's high, anguished voice. Their eighth and final album, Love's Holiday (2023), was their first for Ipecac Recordings; the band dissolved in 2024.

San Francisco shape-shifters who smuggled funk, hip-hop, synth-pop, thrash, lounge and film-score bombast into stadium-sized alternative metal, peaking commercially with The Real Thing (1989) and creatively with the gloriously perverse Angel Dust (1992). When Mike Patton was poached from Mr. Bungle in 1988, the band became the primary launchpad for his sprawling avant-garde universe — making Faith No More the closest thing this atlas has to a mainstream gateway drug. Few bands did more to convince metal that genre borders were optional.

Formed in Montesano, Washington in 1983 around the constant core of Buzz Osborne and Dale Crover, Melvins fused punk with a heavy Black Sabbath influence and in doing so godfathered sludge metal, leaving fingerprints on everything from grunge to doom and stoner rock. Relentlessly prolific shapeshifters, they have cycled through bassists and configurations — including the Kevin Rutmanis era and the double-bass-driven Melvins Lite with Trevor Dunn — while releasing a torrent of albums on Mike Patton's Ipecac Recordings since 1999. Their gravitational pull is such that Japan's Boris took their name from the title of a Melvins song, and collaborators have ranged from Fantômas and Jello Biafra to Lustmord and Napalm Death.

Mastodon is an American heavy metal band formed in Atlanta in 2000, fusing sludge and stoner metal with progressive rock, hardcore aggression and jazz-influenced drumming into an ambitious, concept-driven sound. Their breakthrough Leviathan (2004), a song cycle built around Moby-Dick, established them as one of the most original and influential American metal bands of the 21st century, and later records like Crack the Skye (2009) pushed further into psychedelic prog territory. The classic four-piece held together for 25 years until guitarist Brent Hinds split with the band in March 2025 and died in a motorcycle accident that August; three of the four members trade lead vocals, giving the band its distinctive multi-voiced attack.
