Bad Acid Trip
United States · formed 1989 · last active 2025
A North Hollywood grindcore/crust act formed in 1989 out of the West Coast powerviolence scene, known for splicing manic grind and blast-beat black-metal tremolo with surf-rock detours, jazzy guitar asides, and outright circus-music absurdism, topped by 'make any noise necessary' vocals. Longtime signees to System of a Down frontman Serj Tankian's Serjical Strike Records, with 2004's Lynch the Weirdo produced by SOAD guitarist Daron Malakian; still active into the 2020s with new lineups.

WHY THOSE SCORES
- Jazzy 2 — Slow sections are described as inserting 'jazzy guitar interludes' amid the grind (metalreviews.com review, via search).
- Hardcore 7 — Formed out of the West Coast powerviolence scene in 1989 (en.wikipedia.org/wiki/Bad_Acid_Trip, fetched); Lynch the Weirdo reviewed as 'dissonant Post-Hardcore/Grindcore in the vein of Fugazi and Napalm Death' (metalreviews.com review, via search).
- Surf 3 — A review notes the songs incorporate 'almost surf rock elements' before lurching back into grind (metalreviews.com review, via search).
- Black 4 — Reviews describe 'decently moving tremolo riffs... whenever a blast beat fires up' and 'random influences from classic black metal' (metalreviews.com/Sputnikmusic reviews, via search).
- Technical 3 — Songs deliberately splice grind, jazz, surf and circus-music passages together within single tracks, a compositional patchwork rather than straightforward riffing (metalreviews.com review, via search).

Bad Acid Trip directly supported System of a Down (alongside The Mars Volta) on System of a Down's mid-2005 North American Mezmerize tour — role confirmed on System of a Down's own page ("the band toured extensively throughout the United States and Canada with The Mars Volta and Bad Acid Trip supporting"). A prior chunk fetched this same source for the the-mars-volta tie and incorrectly logged Bad Acid Trip as off-atlas; it is a full atlas node (Daron Malakian already produced its Lynch the Weirdo, existing producer edge) and this tour tie was missed. source ↗
- The Mars Voltapath →
Co-support tie: The Mars Volta and Bad Acid Trip both supported System of a Down on the same 2005 US/Canada tour (per System of a Down's own Wikipedia page: "toured extensively throughout the United States and Canada with The Mars Volta and Bad Acid Trip supporting"). Co-support on a named tour is a tour tie per the 2026-08-07 ruling. source ↗

FURTHER LISTENING

- UnaffiliatedEI 11Final ExitHardcoreTheatricalSurf
Japanese noisecore/noisegrind duo from Kanagawa Prefecture, active since 1994, consisting of Hisao (guitar, vocals) and Ryohei/Kikuchi Ryohei (drums). Final Exit built a cult reputation across dozens of splits and tapes for melding chaotic grind blasts with an earnest love of surf rock, disco, pop and classic rock ('Kiss and Iron Maiden'), often as tongue-in-cheek genre parody. Still active past their 30th anniversary, they premiered a new album at Obscene Extreme festival in 2024 and released a picture-disc LP tribute to Japan's 'Young Guy' (Wakadaisho) film series in 2020.
- UnaffiliatedEI 7MaïsmanTheatricalHardcoreTechnical
Maïsman is a Grenoble collective built around a fictional vegetable-superhero mythology, pitting its titular hero against the villain 'Méchant Man' (voiced on record by Lofofora's Reuno) across two concept albums, Le Plus Grand des Super-Héros (2006) and Le Retour de Méchant Man (2010), blending funk, new wave, synth-pop, hardcore and alternative metal. Live, the project stages a full theatrical production — characters, costumes and sets, a Star Wars/Disney pastiche — making the show, as much as the genre-shifting studio sound, its defining trait.
- Patton-verseEI 8The Jesus LizardHardcoreTheatricalTechnical
Formed in Austin in 1987 and relocated to Chicago in 1989, The Jesus Lizard perfected a blueprint of noise-rock menace: David Wm. Sims and Mac McNeilly's lurching, hydraulic rhythm section, Duane Denison's wiry precision guitar, and David Yow howling from deep in the mix like, in one critic's words, 'a kidnap victim trying to howl through the duct tape over his mouth.' Their Steve Albini-recorded Touch and Go albums Goat (1991) and Liar (1992) stand among the most significant noise rock records of the era, and a split single with Nirvana briefly brushed them against the mainstream. After disbanding in 1999 and reuniting for tours from 2009 onward, they released Rack in 2024, their first album in 26 years.
- UnaffiliatedEI 9Winny PuhhTheatricalHardcore
Winny Puhh are an Estonian punk/metal band formed in 1993 in Põlva, known for a berserk visual spectacle: wolfman masks, spandex wrestling gear, and a custom rigged drum kit that spins two drummers through the air simultaneously. Their 2013 Eesti Laul performance went viral and led to an invitation to perform at Rick Owens' Paris menswear show.
- Patton-verseEI 13Dead CrossHardcoreTheatricalTechnical
Dead Cross is a Southern California crossover-thrash/hardcore supergroup formed in late 2015, uniting drummer Dave Lombardo (Slayer, Fantômas, Mr. Bungle), bassist Justin Pearson (The Locust, Retox), and guitarist Michael Crain (Retox). The Locust's Gabe Serbian was the original vocalist but left after the debut was recorded; Mike Patton replaced him in December 2016, rewriting the vocals over the existing instrumentals. The band has released two albums via Patton's Ipecac Recordings — the self-titled debut (2017) and II (2022) — delivering short, violent blasts of thrash and hardcore punk.
- UnaffiliatedEI 10ClondementtoHardcoreTheatricalBlack
Clondementto is a genre-scrambling rock/metal project from Guadalajara, Jalisco, Mexico, formed in late 2002. Their 2009 album Carnival Complexia is promoted on Bandcamp as a 'free improvisational ride' melding free jazz, black metal, noise rock and lounge into one vision, wrapped in a carnival/commedia-dell'arte concept (track titles reference Polichinella and funhouses). The wider band catalog leans on eclectic Mexican alt-metal blending jazz, funk, bossa nova and rock, but Carnival Complexia specifically is the outlier record where the metal and free-jazz elements are most explicit.
- Dissonant tech-deathEI 107000 Dying RatsHardcoreTheatricalTechnical
7000 Dying Rats are a long-running Chicago 'comedy grind' collective, active in various lineups since 1992, built around joke song titles and a deliberately rotating cast of 30-plus contributors rather than a fixed band. Their records (Fanning the Flames of Fire, The Sound of No Hands Clapping, Season in Hell) mix grindcore/noise aggression with tasteless, cult-favorite humor. The most notable alumnus is drummer/vocalist Weasel Walter, who passed through the Rats between stints leading The Flying Luttenbachers and later drumming for Behold... The Arctopus.
- Post-metalEI 7Made Out of BabiesHardcoreTheatricalTechnical
Made Out of Babies were a Brooklyn noise-rock/sludge quartet active 2004-2012, fronted by the extraordinary Julie Christmas, whose lurching between whisper and shriek gave the band its volatile character. They released Trophy (2005) and The Ruiner (2008), with the Steve Albini-recorded Coward (2006) widely rated their high point; early records came out on Neurosis's Neurot Recordings. The lineup drew from the wider New York heavy underground, with guitarist Brendan Tobin (Red Sparowes), bassist Eric Cooper, and Christmas also fronting Battle of Mice.
- Turner-verse / Hydra HeadEI 4Split CraniumsatelliteHardcoreTechnical
Split Cranium is a trans-Atlantic crust/d-beat/hardcore punk project pairing American musician Aaron Turner (Isis, Sumac, Mamiffer) with Finnish musician Jussi Lehtisalo (Circle). Lehtisalo and Turner conceived the band during Circle's 2009 European tour with Isis, with Lehtisalo writing riffs and Turner adding vocals, guitar, and noise. Their self-titled debut arrived on Hydra Head Records on March 20, 2012, followed by the more experimental "I'm the Devil and I'm OK" on Ipecac Recordings on May 25, 2018. Turner has described the dynamic as "Jussi loves melody and I love dissonance and noise."
- UnaffiliatedEI 17Dog Fashion DiscoTheatricalHardcoreTechnical
Dog Fashion Disco is an American avant-garde metal band formed in Rockville, Maryland in 1995, built around vocalist Todd Smith and long-serving drummer John Ensminger. Frequently likened to Mr. Bungle, they splice heavy metal with jazz, circus and film-noir cabaret, 1960s psychedelia, ska and funk into whiplash, concept-driven records. A saxophone/woodwind chair (Matt Rippetoe) anchors the jazz side of the lineup, and their 2001 major-label album Anarchists of Good Taste features a guest turn from System of a Down's Serj Tankian.
