Isa was a solo Dutch black metal project from Arnhem, active only in 2008, releasing a single limited CD-R, Eindeloos, before disbanding. The record pairs raw, repetitive tremolo riffing with minimal, ambient-tinged guitar textures across three long, depressive tracks dealing with loneliness and isolation. It is a minor, self-contained entry in the Dutch DSBM/atmospheric underground with no documented links to other scene names.

Gelassenheit is the solo avant-garde/atmospheric black metal project of Uncumber (Mave/Abe Goren), based in Brooklyn/New York and active since 2020. The self-titled album blends symphonic black metal, avant-garde metal, dungeon synth, depressive black metal, and coldwave into a synth-heavy sound built around explicitly Christian-anarchist ('Red and Anarchist Black Metal') themes of communal living, care for the poor, and anti-fascism, framed by the artist as 'using Christianity as a tool for advocacy and unique aesthetic cultivation' rather than evangelism. Uncumber is a trans woman and has described the project in interviews as unblack, RABM-aligned black metal.

Crown of Ascension is the solo experimental black metal project of UK multi-instrumentalist A. White (Oxfordshire), who is also the sole member of extreme-metal project Vessel of Iniquity and the industrial/drone/doom project Uncertainty Principle. The project blends blastbeat-driven black metal with industrial, drone and electronic textures, with cello recurring as a primary instrument alongside drum machines pushed to extreme tempos.

Bríi is the electronic-leaning solo alter ego of Brazilian multi-instrumentalist Caio Lemos (aka Serafim), better known for his acoustic-folk black metal project Kaatayra. Where Kaatayra leans on native Brazilian folk instrumentation, Bríi fuses raw black metal blast passages with dark ambient, techno, trance and space-psychedelia, described by one Metal Archives reviewer as an 'improbable' but effective genre collision. Based in Distrito Federal, Brazil, the project has released a string of albums since 2020 via Flowing Downward and Bandcamp, including Sem Propósito (2021) and Último Ancestral Comum (2023).

greyfleshtethered is the solo electronic black metal project of Daria, recording from the Connecticut woods and citing ambient black metal touchstones like Paysage d'Hiver, Neige et Noirceur, Trist, and Arkhtinn. 2021's 'The Dark Being' is an 83-minute, five-track narrative journey through alternate dimensions that blends atmospheric black metal with dark ambient, dungeon synth, and shoegaze textures. Live, the project splits its set between guitar and soundboard-triggered electronics. The project is explicitly framed as trans anarchist and anti-fascist within the black metal underground.

London's Sea Mosquito wrap raw black metal in ambient synth haze and echo-drenched production, favoring atmospheric wash over riff-forward songwriting - tremolo guitar and drums function as background texture behind cascading, almost lead-like drumming. Their 2025 album Majestas (I, Voidhanger Records) explores religious ecstasy across cultures, with harsh vocals occasionally giving way to spoken passages in English and Arabic. They sit closer to psychedelic/atmospheric black metal than to the death-metal-adjacent avant-garde acts on this chart, but the noise-and-texture-first approach is exactly the kind of unorthodox BM the label built its name on.

Edasi is a solo project of M. Kleis from Tallinn, Estonia, self-described as 'experiments in the field of black metal/drone/ritual ambient/noise/psychedelia' and reviewed as 'outsider black metal.' The catalogue spans lo-fi black-noise pieces (Horror Mirror) to the 2009 EP Pikse litaania, which reworks Estonian folk-choral composer Veljo Tormis and medieval composer Hildegard von Bingen into extended, droning, chant-like sound-collage pieces -- described by Boomkat as re-interpreting those composers' work 'through the outsider black metal' of Kleis's own sound.

Project Nefast is a black metal project from Utrecht/Amsterdam, Netherlands, releasing through Tartarus Records, known for an absurdist, nihilism-inflected take on black metal built from 'noise, drone and repetition' rather than straightforward riffing. Key releases include Discomfort (2015), Dogma (2016), Sex Money Power (2017/2018) and NEE (2018); the band has performed at Roadburn Festival. Active as 'Nefast' 2013-2017, renamed 'Project Nefast' 2017 onward.

Murmuüre is a French one-man avant-garde black metal project (sole member Felix Naos) whose enigmatic 2010 self-titled album was assembled over three years from a single one-hour guitar improvisation recorded in November 2006, edited and re-layered into a ritualistic sound collage. The result blends black-metal instrumentation with dark ambient, drone, noise and psychedelic textures — 'a churning, claustrophobic mix of queasy underwater black metal... glitchy, phantom drones'. It was released on Cold Void Emanations and Aurora Borealis Recordings.

Omega Centauri is a UK-based atmospheric black metal project built around multi-instrumentalist Tom Vallely, blending glacial tremolo-riff black metal with dark ambient textures, doom-paced passages, and cinematic post-rock swells. Recorded piecemeal between 2006 and 2011, debut Universum Infinitum favors slow-burn atmosphere and philosophical/theological themes over aggression. The project sits in the same cold-and-spacious atmospheric black metal lineage as labelmates on Duplicate Records.
