miRthkon are an Oakland sextet of two guitars, two woodwinds, bass and drums, self-described as 'an amplified chamber ensemble masquerading as a rock band,' with material fully scored down to the drum parts. Across Vehicle (2009) and Snack(s) (2013) on the Italian AltrOck label, critics describe a satirical, Zappa-inflected collision of thrash riffing, big-band horns, and jazz harmony staged with circus-like theatrical framing. Keyboardist/bassist Matt Lebofsky doubles as keyboardist in Secret Chiefs 3, giving the band a direct, sourced line into the Estradasphere/Secret Chiefs 3 orbit already on the atlas.

Valtozash is a fifteen-to-seventeen-piece 'jazz-thrash-metal' big band out of Brisbane, Australia, led by composer and electric vibraphonist Andre Bonetti. A full horn section collides free-jazz harmony and improvisation with thrash-metal aggression, drawing press comparisons to a conducted orchestra 'brutally assaulting' jazz standards. Albums like Wizard-Bird (2017) and Boiling Solitude (2021) showcase the ensemble's scale, arranging dense big-band charts against metal riffing.

Electrocution 250 was a short-lived instrumental trio from Minnesota — guitarist Todd Duane, keyboardist Lalle Larsson, and drummer Peter Wildoer — who recorded a single album, 'Electric Cartoon Music From Hell' (2003/2004), fusing jazz-fusion virtuosity with Carl Stalling-style cartoon-music motifs and occasional thrash-metal bombast. Larsson and Wildoer are separately known for progressive/metal session and band work (Karmakanic, Darkane, among others), but this project stands as a standalone one-off. It is unrelated to the atlas's Ulver electronic era.

Titan to Tachyons is a New York instrumental quartet led by guitarist Sally Gates, built around a two-bassist frontline (Trevor Dunn and Matt Hollenberg) with drummer Kenny Grohowski, fusing free-jazz improv, prog counterpoint, and metal violence into sci-fi-themed instrumentals. Their 2022 album Vonals was released on John Zorn's Tzadik label (following 2020's Cactides on Nefarious Industries), and the polyrhythmic, two-bass arrangement gives the compositions an unusually dense, contrapuntal low end. Every member's other credits (Mr. Bungle, Fantômas, Tomahawk, Secret Chiefs 3, Cleric, Imperial Triumphant) wire this band into the Zorn/downtown-jazz and Patton-adjacent avant-metal orbit.

Trevor Dunn's Trio-Convulsant is the avant-garde jazz vehicle of Mr. Bungle bassist Trevor Dunn, active since 1997 and built on the idea of a compositional jazz trio that also wields rock's power chords — AllMusic called the result "moody jazz with convulsive rock." The group debuted with Debutantes & Centipedes (1998, Buzz Records) featuring guitarist Adam Levy and drummer Kenny Wollesen, then re-emerged on Ipecac with Sister Phantom Owl Fish (2004) in a new lineup with guitarist Mary Halvorson and drummer Ches Smith. That trio returned on Séances (2022, Pyroclastic Records), expanded by the chamber quartet Folie à Quatre — including Sleepytime Gorilla Museum violinist Carla Kihlstedt — for music inspired by the 18th-century French Convulsionnaires of Saint-Médard.

Cartel Carnage is a French quintet of jazz-scene musicians (guitar, bass, trumpet, tenor sax, drums) fusing free jazz, heavy metal, pop and progressive rock into what reviewers called a 'musical UFO.' Their sound and stated influences — Naked City, Fantomas, Mr. Bungle, Zorn, Ornette Coleman, alongside Meshuggah and Slayer — place them squarely in genre-collision RIO/avant-prog territory, though no sourced personnel or label ties connect them to the existing atlas. Their sole full-length, Incorporated, was released in 2012 on Great Winds/Musea Records.

Tear Light From Matter is a Massachusetts-based instrumental act pairing saxophone with a standard metal rhythm section, self-tagged on Bandcamp as experimental/jazz metal/fusion/prog metal. Their debut, "In Statu Nascendi" (released 25 January 2019, recorded and mixed by Jerry MacDonald at Odd Fellows Recording), sits alongside a further release, "Fœtal Præyers", in a small but pointed discography. The saxophone-led interplay places them in the lineage of jazz-inflected heavy bands rather than straightforward metal songwriting.

Volto! is an American jazz-fusion jam band based in Los Angeles, best known as the side project of Tool drummer Danny Carey. Formed in the early 2000s from improvised sessions with guitarist John Ziegler and bassist Lance Morrison at a San Fernando Valley jazz club, the group spent nearly a decade as a live-only act before releasing its debut album Incitare (2013) on Fantasy Records. Their heady, genre-spinning instrumental sound bridges King Crimson, Liquid Tension Experiment, and 1970s fusion, foregrounding the improvisation that Carey has cited as his main motivation for the project.

The Pitts Minnemann Project is an instrumental progressive-rock/jazz-fusion collaboration between keyboardist Jimmy Pitts (Scholomance) and drummer Marco Minnemann, joined by rotating guest virtuosi on guitar, bass, saxophone, and violin. They released two albums, '2 L 8 2 B Normal' (2014) and 'The Psychic Planetarium' (2016), both blending heavy fusion with progressive-metal complexity.

Brooklyn/NYC instrumental trio blending prog, jazz, and metal into knotty, polymetric compositions; began as an acoustic jazz unit before electrifying into an aggressive math-rock/tech-metal power trio. Drummer Jeff Eber doubles in Dysrhythmia, and the band's Cuneiform-era records were engineered by Dysrhythmia's Colin Marston, tying them into the Brooklyn tech-metal underground.
