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.

Mamiffer is an American experimental band based in Seattle, Washington, founded in 2007 by Faith Coloccia out of ideas from her former group Everlovely Lightningheart. It began as her solo project and grew into a duo with Aaron Turner (of Isis and Sumac), who became her creative partner and later husband; the two also co-founded SIGE Records. The music intertwines ambient, drone, and post-rock composition with piano and ethereal vocals, and the band is known for collaborative albums and rotating guest musicians.

House of Hayduk is the solo/collective vehicle of Düreforsög guitarist Mads Heldtberg. Its 2012 debut City of Quartz (Koolarrow Records) is an instrumental record built from analogue synthesizers, dub-inflected bass and free-form percussion, evoking a Blade Runner-style dystopia (the title nods to Mike Davis's book on Los Angeles). Faith No More bassist Billy Gould performs on the record, alongside This Heat's Charles Hayward.

Terra Tenebrosa were a masked, pseudonymous Swedish avant-garde/industrial black metal project from Stockholm (2009-2021), fronted by 'The Cuckoo' (Tomas Hallbom) alongside 'Hisperdal' and 'Hibernal.' Rising out of the ashes of cult post-hardcore band Breach, their three albums - The Tunnels (2011), The Purging (2013), and The Reverses (2016) on Debemur Morti Productions - combine black metal shrieks with industrial noise, sludge-doom heaviness, and dark-ambient drone. The Cuckoo's own history gives the band a direct, sourced tie to the atlas: he was a member of The Ocean (as 'The Ocean Collective,' 2004-2007) and appeared as one of the credited guest vocalists on The Ocean's 2006 album Aeolian.

Kollektiv Raumordnung is a German multimedia art collective led by Moritz Fabian, involving 20+ collaborators across music, writing, photography, and visual art. Their debut album 'Stewards of Eon' (Dec. 2025, Fucking Kill Records/Cultkill Music) merges war metal, dark ambient, opera, power electronics, and psytrance into a single sci-fi concept release accompanied by a graphic novel, positioned as a 'twin-entity' sharing a fictional universe with the German doom act Eremit.

Midnight Odyssey is the one-man cosmic/atmospheric black metal outlet of Brisbane's Dis Pater, running concept albums soaked in mythology since 2007. Its sprawling Biolume trilogy (2019-2023) folds synth-driven ambient drone, neoclassical arrangement, and doom-metal pacing around a core of raw, lo-fi black metal. The project regularly spins off pure ambient/ kosmische material and symphonic re-recordings alongside the metal proper, making atmosphere as central to its identity as riffs.

Haiku Funeral is a ritualistic industrial/black-metal-adjacent project born in a Marseille studio on Halloween 2008, built around Bulgarian multi-instrumentalist Dimitar Dimitrov (electronics, keyboards, vocals) and American bassist/vocalist William Kopecky, with Finnish drummer David Lillkvist also credited on record. Their sound is a hallucinogenic blend of occult drone, droning doom, and cinematic/ritual ambient, colored by theremin, e-bow, spring-drum, children's harp, and sitar - one reviewer singled out the sitar-and-tribal-percussion 'Cherni Shamani' as evoking cyber-shamanic trance. Six albums deep (most recently Drown Their Moons in Blood, 2021, via Aesthetic Death), they occupy a genuinely fringe niche between black metal atmosphere and psychedelic ritual ambient.

Nazoranai is an improvising power trio formed in 2011 by Keiji Haino (guitar, vocals, synth), Stephen O'Malley of Sunn O))) (bass) and Oren Ambarchi (drums), issuing its self-titled live debut on O'Malley's Ideologic Organ imprint in 2012. The name signals a stance against pure free improvisation, favoring a more deliberate approach as the trio moves from sparse, post-industrial landscapes into huge firestorms of riff and distortion. Its genesis traces to a 2006 introduction between Haino and O'Malley via Ambarchi.

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.
