Deathspell Omega

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.

Kexelür is a Santiago, Chile trio formed around 2021 playing atmospheric, dissonant, and psychedelic black metal built around free improvisation. Their releases are billed as largely improvised live sessions, with reviewers noting 'jazz fusion inspired soloing/leads' layered over the black metal foundation. The band communicates only through single-letter pseudonyms (Λ., V., J.), with Λ. also running the solo project Fatalys (not in the E.M.M.A. atlas).

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.

Aenaon is a Greek avant-garde/progressive black metal band from Ioannina, formed in 2005 and signed to Agonia Records. Mastermind Achilleas C. (also of Varathron and Katavasia) leads the band with drummer Haris (Varathron), vocalist Astrous (Katavasia) and saxophonist Orestis Zyrinis, whose horn work gives their dark, noir-tinged black metal a distinctive jazz-inflected edge, as heard on 2022's 'Mnemosyne.'

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.

Altari is an Icelandic black metal band whose debut album Kröflueldar, released via Svart Records in April 2023, took roughly nine years to complete. The record folds clean, melodic guitar leads and influences from Blue Öyster Cult, Killing Joke and Interpol into a black metal foundation, co-produced by Stephen Lockhart (aka Wann), a central engineer/producer figure in Reykjavík's black metal scene.

Aryos is a long-running French avant-garde black metal act from Ussac/Brive-la-Gaillarde (Corrèze), formed in 1994 (originally as Forlorn, renamed 1997). Built around an occult/esoteric concept by members using the stage names Napharion, Pétal and Alilteas Gornnec, their sound layers jazz-tinged synths, classical piano and prog-rock textures over a black metal core. Later releases like Les Stigmates d'Hécate (2015) lean into atmospheric, folk-tagged textures.

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.

Wyrmwoods is a one-man experimental/atmospheric black metal project from Oulu, Finland, active since 2014 under the alias Nuurag-Vaarn and signed to Inverse Records. Its four full-lengths (Earth Made Flesh, 2017; Spirit & Teeth, 2019; Gamma, 2020; No Sun Nor Moon, 2022) fold progressive rock, doom, jazz saxophone and ambient texture into a black metal core, with Gamma marking a deliberate turn from a chaotic, lo-fi approach toward more progressive, Opeth-indebted songwriting.
