- Blackgaze / avant-blackEI 12DenigrataAmbientBlackGlitch
UK avant-garde black metal collective from Northampton (active 2014-2019), fronted by Denigrata Herself and built around dual operatic/harsh vocals, mechanised industrial drum programming, piano and ambient synth textures under a symphonic black-metal core. Their sole full-length, Missa Defunctorum: Requiem Mass in A Minor (2015), self-tags 'ambient, glitch, noir concrête' and drew Blut aus Nord/Anaal Nathrakh comparisons for its atmospheric density.
- Blackgaze / avant-blackEI 16UmbrtkaBlackAmbientDoom
Umbrtka is a prolific Czech black/doom/industrial project from Plzeň, active since 1999 and centered on a self-invented industrial deity presiding over the city's factories, railways and scrapyards. Their 'grey metal' sound layers dissonant black metal with field recordings, mechanical noise and surreal spoken-word narration. František 'Franta' Štorm — closely associated with Czech black metal pioneers Master's Hammer — served as a past vocalist.
- Norwegian avant-blackEI 16PeccatumBlackAmbientTechnical
Norwegian avant-garde project (1998-2006) from Notodden founded by Ihsahn (Emperor), his wife Ihriel and her brother Lord PZ, on their own Mnemosyne Productions. It began as symphonic avant-garde extreme metal and drifted toward classical-tinged avant-garde rock full of twisted synths, electronics, operatic female vocals and Ihsahn's shrieks. Lost in Reverie (2004) is regarded as a landmark of the genre-transcending Norwegian avant-garde.
- UnaffiliatedEI 13Hail Spirit NoirAmbientBlackTechnical
Hail Spirit Noir is a Greek band from Thessaloniki (formed 2010) that welds 1970s psychedelic and progressive rock — vintage organ, synth and mellotron textures — onto a modern second-wave black metal frame. Founded by Haris and Theoharis, both veterans of the prog outfit Rex Mundi and the avant/symphonic project Transcending Bizarre?, the band cultivates an occult, horror-tinged atmosphere across concept albums, drifting further into synth-forward territory on Eden in Reverse. Frequently filed alongside Oranssi Pazuzu and Arcturus as psychedelic/avant-garde black metal.
- UnaffiliatedEI 13SaprovoreBlackAmbientTechnical
Saprovore is the solo industrial black/death metal project of an Italian musician also known for the band Strigiform, released through I, Voidhanger Records. His album 'Numinous Abditory Deflagration' (2026) is described by the artist as exploring 'cosmic emptiness' with a more refined, symphonic-leaning songwriting approach than his debut 'Unuttered Aporetic Omen.' Cited influences include Gnaw Their Tongues, Jute Gyte, Blut Aus Nord, and Thantifaxath (stated influences, not collaborations).
- UnaffiliatedEI 18TodesstoßAmbientBlackGlitch
Todesstoß is the solo experimental black metal vehicle of German musician, poet and painter Martin Lang, active out of Munich since the early 2000s. Releases like Hirngemeer and the 46-minute single-track Ebne Graun fold harmonica, funeral-doom pacing and abrasive electronic texture into a deliberately disorienting, self-willed strain of black metal, released via I, Voidhanger Records.
- UnaffiliatedEI 16LeukotomyAmbientBlackTheatrical
Leukotomy was a black metal duo from Hanoi, Vietnam, formed in late 2020 and active until 2023. Their sole full-length, 'Eternal Path to Eden' (House of Ygra, March 2023), is a nine-part conceptual 'tragedy' set in a gothic world, blending second-wave black metal aesthetics with avant-garde, noise, and ambient elements to tell a story of vengeance, mental torment, and unrequited love. The album was produced by Imperial Cult (Elcrost), mastered by Nemo Lockeheart, and features spoken-word passages by Sam Tang.
- Southern Lord / droneEI 26Runhild GammelsæterAmbientTheatricalBlack
Runhild Gammelsæter is a Norwegian vocalist who is also a professional biologist holding a Ph.D. in cell physiology. She first drew notice fronting the American doom band Thorr's Hammer, which she joined at 17 alongside Stephen O'Malley and Greg Anderson, and later co-formed the duo/trio Khlyst with James Plotkin. Her 2008 solo debut Amplicon (Utech Records) is built almost entirely from her own voice, warped with effects, with each track founded on a scientific, largely biologic theme conceived as a soundtrack to the cycle of the universe. Her voice ranges from the death-metal growls of her Thorr's Hammer work to unnerving, art-inflected experimental singing.
- Blackgaze / avant-blackEI 25Cloak of AlteringBlackGlitchAmbient
Cloak of Altering is the avant-garde black metal solo alias of Dutch multi-instrumentalist Maurice "Mories" de Jong, begun in 2011 as a continuation of his earlier black metal band Ophiuchus and run alongside his other projects Gnaw Their Tongues, De Magia Veterum, Aderlating and Seirom. Where De Magia Veterum is his straight black-metal outlet, Cloak of Altering fuses 'mutated symphonic black metal' with breakcore-derived electronics and industrial noise, inviting comparisons to Blut Aus Nord and An Axis of Perdition. Albums such as Plague Beasts (2014) and Manifestation (2015), released via Crucial Blast, circle cosmic and occult themes across sprawling, drone-heavy tracks.
- UnaffiliatedEI 16La Torture des TénèbresAmbientBlackGlitch
Solo raw black metal project of Ottawa multi-instrumentalist Jessica Kinney, running since 2016 across roughly eight releases including full-lengths and splits. The sound layers harsh, noise-caked black metal against warped, decayed ambient passages, earning press comparisons to Sutekh Hexen, Gnaw, and dark-ambient artist The Caretaker. Albums build a recurring retro-futuristic, dystopian mythos described by Vice as 'Metropolis meets Victorian death cult.'
