OLD

Phantomsmasher is a glitch-grind / digital-hardcore project led by guitarist James Plotkin, previously known as Atomsmasher, that fuses grindcore with electronic noise and cut-up programming. The trio of Plotkin (guitar, bass, electronics), vocalist DJ Speedranch, and drummer Dave Witte released their self-titled album on Mike Patton's Ipecac Recordings on August 19, 2002. Plotkin is a prolific experimentalist also known for OLD, Khanate, Khlyst, Jodis, and Scorn.

Umbah is the solo avant-garde industrial death metal/cybergrind project of UK multi-instrumentalist Cal Scott (formerly guitarist of grind act Necrosanct), running since 1990 and released largely through I, Voidhanger Records. Extremely prolific (dozens of albums across sci-fi/absurdist concept releases like 'Continuum,' 'Xominod,' and 'Obliticus'), the project fuses industrial death/grind with harsh electronics and jazz-tinged arrangements into what reviewers call 'techno-organic metal.'

precettö is the solo avant-garde metal project of Auckland, New Zealand musician Jessie Edwards (performing as Drella), a self-produced one-person operation covering 'each instrument, sample, screech, and act of fuckery' on their own recordings. Emerging from an online shoegaze/Y2K-aesthetic scene, the music collides progressive and dissonant death metal, digital hardcore, cybergrind, breakcore and glitch electronics with ambient and shoegaze passages, resisting any single genre label (the artist's own tagline: 'i do not make prog metal'). Recent releases include Siddhartha (2025) and Siddhartha 2 (2026), the latter covered by Heavy Blog Is Heavy as a 'lovable mess of electronic and metal' engaging themes of neurodivergence and queer/trans identity.

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.

Gigantic Brain is a Virginia-based cybergrind project started by John Brown in the early 2000s as one-man, drum-machine-powered electronic grindcore, later expanded into a duo with producer/multi-instrumentalist Mastin Simmons in 2012. Wikipedia credits it as 'one of the original pioneers of the cybergrind subgenre,' with a catalog running from chaotic, densely layered electronic grind (The Invasion Discography, 2004) toward the industrial/doom/ambient-leaning textures of the 2016 self-titled album. Released mostly through Razorback Records and Grindcore Karaoke, with absurdist lyrical themes layered over extremely dense production.

Corrections House is an American industrial-sludge supergroup formed in 2012, bringing together Scott Kelly of Neurosis, Mike IX Williams of Eyehategod, Sanford Parker, and Bruce Lamont of Yakuza. The group methodically creates and destroys through dark, apocalyptic soundscapes built from riffs, saxophone, electronic loops, and Williams' corroded vocals. They released their debut album Last City Zero (2013) and its follow-up Know How to Carry a Whip (2015) on Neurot Recordings.

Patau is a Boston, Massachusetts noise/industrial project self-described as 'experimental electronic hardcore techno industrial metal noise,' with Rate Your Music tagging it Avant-Garde Metal, Power Noise, and Experimental. Releases include Krrrenž (2018) and Not One, Not Some, Not All (2021), delivered with confrontational, anti-capitalist framing.

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.

Fawn Limbs are a transatlantic mathcore/deathgrind project formed in 2018 by guitarist-vocalist Eeli Helin and drummer Lee Fisher (ex-Psyopus, Commit Suicide), later joined by bassist Samuel Smith (Artificial Brain). Their catalog fuses grind tempos, mathcore's unusual time signatures, and noisy electronics, and their 2023 collaborative LP Vestigial Spectra with drone/doom act Nadja pushed the project into sustained-drone and abrasive-ambient territory. Drummer Lee Fisher's stint in Psyopus (2004-2005) is a direct, sourced tie into the mathcore cluster already on the atlas.

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.
