Zeni Geva are a Japanese noise-rock band formed in Tokyo in 1987 by guitarist-vocalist KK Null (Kazuyuki Kishino), built on brutal, minimalist, detuned riff-machines and Null's harsh electronics. Steve Albini produced their 1991 album Total Castration and performed on the 1993 live document All Right You Little Bastards, and Jello Biafra released them on Alternative Tentacles; their 2001 album 10,000 Light Years appeared on Neurosis's Neurot Recordings. The long-running trio settled around Null, Ruins drummer Tatsuya Yoshida, and (for over two decades) guitarist Mitsuru Tabata.

Godflesh are an English industrial metal band from Birmingham, formed in 1988 by Justin Broadrick and G.C. Green, evolving out of the earlier group Fall of Because. Through their fusion of hip hop-derived drum-machine programming, downtuned metal riffs, and industrial dissonance - heard on their acclaimed debut album Streetcleaner (1989) - they developed a sound widely regarded as foundational to industrial metal and post-metal. Broadrick had earlier drummed in Napalm Death, and the band signed to Earache Records before disbanding in 2002 and reuniting in 2010.

Human Impact are a New York noise-rock supergroup formed in 2019, welding Chris Spencer's Unsane fury to Jim Coleman's Cop Shoot Cop-derived industrial electronics. The debut lineup added the Swans rhythm section of Chris Pravdica and Phil Puleo; their self-titled debut appeared on Mike Patton's Ipecac Recordings in 2020, followed by Gone Dark (2024). By 2024 the rhythm section had turned over to ex-Daughters drummer Jon Syverson and ex-Made Out of Babies bassist Eric Cooper.

Zozobra is an American sludge/post-metal band conceived in 2006 by bassist-vocalist Caleb Scofield (Cave In, Old Man Gloom), taking its name from the giant effigy burned annually at the Fiestas de Santa Fe in New Mexico. It gave Scofield his first outlet to write his own songs, and its debut album Harmonic Tremors (2007) featured Old Man Gloom drummer Santos Montano; the band toured the U.S. with Isis and Jesu in early 2007. Later releases Bird of Prey (2008, with Aaron Harris of Isis on drums) and Savage Masters (2013) followed, with the project ending after Scofield's death in 2018.

Old Man Gloom is an experimental sludge/post-metal supergroup formed in 1999 in Santa Fe, New Mexico by Aaron Turner (Isis) and drummer Santos Montano, later expanding with musicians from the Boston hardcore and metalcore scene. Their music juxtaposes crushing sludge and hardcore with noise, drone, and ambient soundscapes. Bassist/vocalist Caleb Scofield died in a car accident in March 2018; Stephen Brodsky, his Cave In bandmate, subsequently joined the band. Their albums have appeared on labels including Hydra Head Records (and its Tortuga imprint), founded by Aaron Turner, as well as Profound Lore.

Chat Pile are an American noise-rock/sludge-metal band from Oklahoma City, formed in 2019, whose members perform under pseudonyms Raygun Busch, Luther Manhole, Stin and Cap'n Ron. Their self-produced 2022 debut God's Country, released on The Flenser, became a surprise breakout, pairing bleak, regionally specific lyrics with abrasive riffing indebted to Big Black. The band followed it with Cool World in 2024.

Greymachine is an experimental industrial noise project formed in 2006, built around Godflesh and Jesu frontman Justin Broadrick and Isis frontman Aaron Turner, with bassists Dave Cochrane (Head of David) and Diarmuid Dalton (Jesu). Broadrick described it as needing "something black to Jesu's white," pairing crushing beats, dissonant guitar, and harsh electronics. Their debut album Disconnected was produced by Broadrick and released on 4 August 2009 via Turner's label Hydra Head Records.

Abishai is the lo-fi noise-rock vehicle of Torrance, California multi-instrumentalist Abishai Smith (aliases DJ Bathtub, Eden, Mizpah), who splatters feedback, drum machines, and kazoo across deliberately unpolished sludge, no wave, and noisecore excursions. The 43-track 'Raw and Legendary!!!' (2017) is a maximalist, comedic blowout of punk-metal bits, while the wider catalog under various aliases swings into death industrial, drone, power electronics, and ambient territory — DIY extremity closer to a bedroom noise scene than conventional metal songcraft.

Killing Joke are an English post-punk band formed in Notting Hill, London in 1979, whose 'tension music' fused aggressive rhythms with gothic, industrial and metallic weight across landmark records like Night Time (1985) and Pandemonium (1994). Frontman Jaz Coleman's apocalyptic delivery and the band's dense, dubwise heaviness made them a widely cited influence on industrial and alternative acts including Metallica, Nirvana and Nine Inch Nails. Longtime bassist Paul Raven, who joined in 1982, was later briefly recruited for a planned Godflesh US tour that collapsed before it began.

Cult of Luna is a Swedish post-metal band formed in 1998 in Umeå, emerging from members of the local hardcore group Eclipse. Widely regarded as a leading force in post-metal alongside Neurosis and Isis, their songs are long, slow and crushing, layering heavy distorted passages with orchestral interludes and post-rock-esque forays. Their discography includes Salvation (2004), Somewhere Along the Highway (2006), and the Metropolis-inspired Vertikal (2013). In 2016 they released the space-themed collaborative album Mariner, recorded with American vocalist Julie Christmas.
