SkyThala are an anonymous American avant-garde/symphonic black metal trio from Tennessee, part of the cryptic Moonlight Cypress Archetypes collective, who debuted with 2022's Boreal Despair on I, Voidhanger Records. Their music fuses the Stravinsky-descended dissonance of Russian modernist classical music with an Emperor-derived symphonic black metal blueprint, weaving oboes, bassoons and trombones through ultra-heavy dissonant-death riffing. The result is a maximalist, sensory-overwhelming collision of 'high art' orchestration and extreme-metal savagery.

Porta Nigra is a German avant-garde black metal band founded in Koblenz in 2010 by Gilles deRais (guitars, bass) and drummer/vocalist O., who recorded the first two albums as a duo before expanding to a full band. Their concept records — Fin de Siècle (2012), Kaiserschnitt (2015), Schöpfungswut (2020) and Weltende (2023), the last inspired by World War I — move between straightforward black metal fury and more psychedelic, spoken-word-laced detours, released through Soulseller Records. Guitarist Gilles deRais has described the project as a way of channeling 'old spirits' through the music.

Thecodontion is a Rome-based black/death metal band formed in 2016 around the unusual choice to abandon guitars entirely, building their sound from two finger-picked distorted basses (plus a third for solos), drums, and vocals. Their releases, including the 2020 full-length Supercontinent on I, Voidhanger Records, follow a 'prehistoric metal of death' concept tracing Earth's continental drift and ancient lifeforms. Reviewers note the band moved from a rawer black/death attack toward a more atmospheric, minimalist, and surprisingly melodic sound, punctuated by bass-driven ambient instrumental passages.

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).

Ævangelist is a US-based avant-garde black/death metal duo formed in 2010 by Matron Thorn and Ascaris, known for folding saxophone and cello into a nightmarish, dissonant sound. In 2016 the pair released the split EP Codex Obscura Nomina with Blut Aus Nord on Debemur Morti Productions.

French duo led by multi-instrumentalist Slo (guitars/drums/vocals/keys) with bassist Camille Giraudeau, playing avant-garde/progressive post-black metal descended from Emperor, Ulver, Borknagar and Ved Buens Ende. After a 12-year gap between albums, 2025's Ruina Draconis (I, Voidhanger) piles on 'extremely layered', ambient-electronic interludes between bursts of blackened violence. Giraudeau's parallel work in Dødheimsgard's touring lineup, Doedsmaghird, Stagnant Waters and Void ties Smohalla directly into the same avant-black/noise diaspora.

Nomicon was a Helsinki act led by vocalist/bassist Tommi Launonen (Ceasar), moving from an early death/thrash sound into symphonic, atmospheric black metal by the 2001 album Halla, drawing comparisons to The Kovenant's Nexus Polaris but 'enriched with more deeply doomy atmospherics.' The band drew on a deep bench of Finnish extreme-metal talent, including guitarist Roope Latvala (later Children of Bodom), rhythm guitarist Miika Niemela (Shape of Despair), female vocalist Tanya Kemppainen (Lullacry), and drummer Yka 'Agathon' (Barathrum). A Metal Archives review characterizes Halla's keyboard-led sound as a 'misanthropic baroque celebration' anchored by 'apocalyptic witch-esque rasps.'

Ebonylake are a UK avant-garde gothic/black/death metal band from Ossett, West Yorkshire, formed in 1997 by vocalist/guitarist/keyboardist Ophelius and drummer Sighmon W. Their 1999 debut On the Eve of the Grimly Inventive (Cacophonous Records) fused technical black metal with avant-garde classical influences (Penderecki, Prokofiev) and horror-film scoring. The band went dormant after 2000, reunited around 2009, and released a second album, In Swathes of Brooding Light, in 2011/2012.

Old Man's Child is a Norwegian symphonic/melodic black metal band formed in Oslo in 1993 (out of the earlier death/thrash outfit Requiem), and effectively the vehicle of sole permanent member Galder (Thomas Rune Andersen), who later also joined Dimmu Borgir. Their sound welds tremolo-driven melodic black metal to early-death-metal influence and symphonic keyboard orchestration, with a classic lineup that included drummer Tjodalv and guitarist Jardar. For the third album, Ill-Natured Spiritual Invasion (1998), Galder brought in American drummer Gene Hoglan as a session player, recording at Sunlight Studio in Sweden with Tomas Skogsberg.
