Ebonillumini is a female-fronted avant-garde/gothic black metal project from London, founded in 2008 by Meads of Asphodel guitarist James Tait ('The Monk Marshall') alongside vocalist Christina Poupoutsi ('The Maiden'). Across The Ebon Channel (2008), Pacificum (2013) and Arktos (2015) the band frames each record as a concept-driven geographic voyage, pairing Poupoutsi's operatic, 'musky' clean vocals against Tait's harsh growls, with reviewers noting jazz-inflected song structures, neo-classical/symphonic orchestration and black-metal-rooted riffing shading into psychedelia and Viking-metal tropes. Production has drawn criticism for burying the heavier material under brickwalled mastering and overlong running times.

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).

Alfa Obscura is a one-man Norwegian black metal/avant-garde project based in Oslo, run since around 2010 by Bjeima (Bjørge Eide Martinsen), who writes, performs, and produces all instruments and vocals. Musically it is rooted in cold, dissonant '90s Norwegian black metal tradition pushed into more avant-garde territory across the albums 'Plutonian Shores' (2011) and 'Sisyfos Speil' (2023), the latter drawing critical comparisons to Ved Buens Ende, Virus, and Manes. Bjeima is also a session/touring bassist for the Norwegian avant-garde black metal band Virus, appearing on their album 'The Agent That Shapes The Desert' (2011) and 'Oblivion Clock' EP (2012).

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.

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.

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.'

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.

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.

Lengsel are a Norwegian progressive/avant-garde 'unblack' metal band formed in 1995, whose 2000 debut Solace won a following for its atmospheric, experimental take on black metal. The band is tightly bound to Extol: guitarist Tor Magne Glidje joined Extol in 1999 (first on bass, later guitar) and, over time, all three Lengsel members became members of Extol. The overlap left Lengsel a largely studio-bound project.

Chicago's Murmur mutate black metal's frost into something stranger, threading Moog synths, jazz-inflected dissonance, and Midwest punk urgency through shrieked, tremolo-driven songwriting. Where peers double down on cold atmosphere, Murmur's albums (2010's Mainlining the Lugubrious, its 2014 self-titled follow-up) reach for space-rock sprawl and noise-rock grit instead. The result sits closer to post-black-metal's outer edges than to any orthodox scene.
