Drainbow is the Austin, Texas one-man vehicle of multi-instrumentalist Nicholas Sarcophagus, who writes, performs and records everything himself. Its debut full-length 'The Tower of Flints' (2020) careens between thrash riffing, doom weight, gothic atmosphere, jazz-tinged lounge interludes and ambient post-metal passages inside a single kaleidoscopic record. It occupies the DIY, one-person-band corner of the avant-garde metal scene, prioritizing eclectic mood-shifting over any single subgenre identity.

Atrorum is a two-person avant-garde/progressive black metal project from Munich, Germany, formed in 1998 by vatroS (guitars, bass, clean vocals, programming) and umbrA (vocals, keyboards, programming). Across three albums on Apathia Records — most notably 2015's Structurae — the band folds symphonic black and death metal into gothic organ, choir, cabaret, funeral-doom, jazz, and industrial-electronic passages, alternating harsh and clean vocals delivered in French, German, and English.

Back to R'lyeh is a Madrid progressive/avant-garde metal band formed in 2011, building Lovecraftian Cthulhu Mythos concept albums out of genre-hopping riffs that swing from black and death metal aggression into funk, jazz-tinged chords, and theatrical, multi-voiced vocal performances. Critics have compared their unpredictable, vocally chaotic style to Mr Bungle, Sigh, and System of a Down.

A prog-extreme-metal supergroup uniting Jason McMaster (Watchtower, Dangerous Toys) on vocals, Davide Tiso (Ephel Duath, Botanist) on guitar, and Hannes Grossmann (ex-Necrophagist, Alkaloid) on drums, Howling Sycamore melts thrash, black metal, and old-school prog-metal singing into dense, riff-heavy epics. Their two albums draw a deep guest bench — Marty Friedman and Kevin Hufnagel (Gorguts, Dysrhythmia) on lead guitar, Bruce Lamont on baritone sax — that pulls the sound toward technical/progressive metal more than cross-genre experimentalism. Jamie King of Between the Buried and Me mixed and mastered the sophomore record, Seven Pathways to Annihilation.

Goatchrist is the solo vehicle of Leeds, UK musician Jacob Guilherme, formed in 2014, an explicitly occult project layering piano, orchestral textures, and jazz-inflected instrumental passages over an Orthodox black-metal core.

Blutmond is a Swiss avant-garde black metal band from Olten, active since the early 2000s, whose lineup includes saxophonist/guitarist Marc (also of Schammasch) alongside vocalist-guitarist John, vocalist-bassist Jerry, guitarist Simon and drummer Fabio. Beginning as a more straightforward black metal act (Endzeit, 2006), the band pivoted toward genre-blending 'urban mysticism' on Thirteen Urban Ways 4 Groovy Bohemian Days (2010) and The Revolution Is Dead! (2012, Code666), the latter folding saxophone, jazz and post-hardcore textures into black metal and drawing guest vocal spots from Anna Murphy (Eluveitie), Managarm (Varg), Markus Baltes (Autumnblaze) and Fredy Schnyder (Nucleus Torn).

Ashenspire is a Glasgow avant-garde/progressive black metal act formed in 2015, one of Scotland's most distinctive experimental metal bands. Their acclaimed 2022 album 'Hostile Architecture' (Code666) welds black-metal dissonance to avant-garde jazz, weaving saxophone, violin, Rhodes and prepared piano beneath vocalist Alasdair Dunn's Sprechstimme delivery. Lyrically it is a scathing, class-conscious critique of late capitalism, gentrification and urban design.

Epectase is a Paris duo that folds frantic tremolo-picked black metal into long-form suites of 70s prog, jazz-tinged interludes, and hazy krautrock electronics, sliding between shrieks, operatic cleans, and meditative ambient passages within a single track. Since forming in 2018, multi-instrumentalist Vague and vocalist Avitus have released a steady run of albums and EPs on I, Voidhanger Records and Frozen Records, sitting among the more overtly progressive-rock-indebted corners of the French avant-black underground.

Epistasis is a New York-based experimental black metal quartet distinguished by Amy Mills' vocals and trumpet, splicing modern-classical dissonance (cited influences: Bartok, Ligeti, Part) and avant-jazz color into abrasive, atmospheric black metal. Their 2014 Crucial Blast album 'Light Through Dead Glass' was engineered by Martin Bisi (Sonic Youth, Swans) and drew press comparisons to Ved Buens Ende and Virus for its dissonant, jagged songwriting. Drummer Alex Cohen also plays in Pyrrhon and Malignancy, and Mills has guested on trumpet for Castevet and Psalm Zero — none of which are in the current atlas.

Lychgate is a London-based avant-garde black/doom metal band formed around 2011-2012, built on a foundation of pipe/church organ used as the compositional backbone of every track. Their influences span late-19th/early-20th-century art music, Rock in Opposition and musique concrete. They record for Debemur Morti Productions, with a discography running from the 2013 self-titled debut through 2025's 'Precipice.'
