Nefarious Mash

A Paris-based avant-garde black metal collective built around composer Thibault Schwartz, integrating 'electro-jazz to black metal' across a large ensemble with violin, cello, clarinet, keyboards and dual male/female vocalists. Fans have described the sound as 'avant-garde black with circus metal and symphonic elements' — a baroque, maximalist take on black metal rather than a straight genre exercise. Dormant since its sole full-length, Introspection (2012).

Arkheth is the long-running (2001-present) Australian project of Tyrone 'Tyraenos' Kostitch, now a one-man vehicle for symphonic-turned-experimental black metal after growing out of the Orange, NSW band Eternal Dark. Its 2018 high point, 12 Winter Moons Comes the Witches Brew, folds saxophonist Glen Wholohan's honking, Contortions-indebted jazz lines into black-metal songwriting critics have dubbed 'an inverted Shining' -- black metal wading into jazz rather than the reverse. It is one of the more distinctive jazz/black-metal hybrids operating outside the Norwegian axis the label comparison implies.

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.

Neon Scaffold is a Russian avant-garde/blackened metal project from Sergiyev Posad, Moscow Oblast, formed in 2018 by musicians drawn from Cage of Creation, Zatemno, and Licho. Their sound mixes jazz-inflected walking bass and saxophone with dissonant, folk-rooted black metal riffing; their 2025 album Noir (Pest Productions) followed a 2020 split, Konflikt, with Polish band Gruzja.

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).

Inquisitor were a Vilnius, Lithuania avant-garde black metal band active 2002-2016, best known for the concept album The Quantum Theory of Id (2010), a four-part metaphysical narrative pairing harsh black-metal riffing with jazzy/spooky acoustic piano and disjointed, technical song structures. A 2014 follow-up, Clinamen | Episteme, continued in the same 'progressive, complex and extremely dynamic blackened metal' vein. They are a niche entry in the Lithuanian black metal underground with no documented ties to other EMMA atlas acts.

Morpheus Tales is a Greek experimental/progressive black metal project from Thessaloniki, built around core member Paris (guitars, drums/keys programming) with Georgios P on guitars and Lee on vocals for their most recent work. Their music is billed as 'avantgarde post black metal' that's psychedelic, strange and concept-driven — 2014's Secular Noir is a 'cosmic noir tale of greed and lust,' while 2017's II is an 8-chapter concept record about hypocrisy, false prophets and the denial of reality, featuring a guest saxophone part from Orestis Exidaris. The project appears self-released/unsigned, distributing exclusively through its own Bandcamp.

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.

Deathspell Omega is an anonymous French black metal collective, formed in 1998, that turned from orthodox raw black metal into one of the most cerebral, theologically-preoccupied acts of the 'dissonant' avant-black wave. From Si Monumentum Requires, Circumspice (2004) and Kénôse (2005) onward their music folds jazz-derived chord voicings, math-rock complexity and dark-ambient/choral interludes into blast-driven black metal. The band never confirms its lineup, so personnel details are limited to widely-reported names.
