Endolith

Voidstar Nocturnal is a progressive blackened death metal trio from Heredia, Costa Rica, formed in 2023 by musicians from Corpse Garden, Deiphago and Advent of Bedlank-adjacent scenes, evolving directly out of Corpse Garden. Guitarist Fabian Salas, bassist Kevin Moran, and drummer/synth player Erick Mejía Arguedas, joined by guest vocalist Roy Zumbado Cognuchz (TŴR, Advent of Bedlam), recorded the debut LP "Nexus Teleport Fracture" (Godz ov War Productions, 2026) live over three days at Colin Marston's Menegroth Studios in New York with no edits, triggers, or overdubs. Critics describe a surreal, psychedelic fusion of dissonant death/black metal with electro-industrial synths, post-punk/darkwave atmosphere, and a cosmic sci-fi/occult concept.

GuilThee is a cultic Hungarian eclectic-metal band from Veszprém, founded in June 2006 by multi-instrumentalist Nagaarum (Gábor Tóth), evolving from thrash/groove/death metal into experimental/progressive metal. Their sound folds in tenor saxophone via longtime member Mr Match, synth-carpet atmospheres, and black-metal/dark-ambient textures across albums including Lustration (2009), Homunculus Paradoxon (2011), Szemantikai háromszögek (2012) and Eklektika (2013).

If Nothing Is (stylized/credited as INI on Metal Archives) is a Trondheim, Norway avant-garde metal project fronted by vocalist Boeddelen, guitarists Håkon Grytvik and Mats Stenberg, drummer Vegard Myrdal Berg, and bassist/main composer Lars Emil Måløy — also the bassist of Dødheimsgard. Emerging from the ashes of an earlier band called Revocation around 2008, the group self-released its sprawling, ten-track debut "If Nothing Is" digitally in 2015, later remixed, remastered and issued physically by Dark Essence Records in 2021 with a guest synth/sample contribution from Dødheimsgard's Vicotnik. The record moves through thrash, speed, death and black metal within long-form, technically demanding compositions compared to early Atheist and Cynic.

Yawn is an instrumental Oslo five-piece that treats extreme metal as a jumping-off point for collective free-jazz improvisation, splicing heavy-as-hell riffing and brutal breakdowns with synth-laced electronics and loose, improvised guitar soloing. Formed in 2019, their DIY-recorded 2022 debut 'Materialism' (Mindsweeper Records) drew acclaim from prog and jazz press alike for treating metal orthodoxy as raw material for real-time reinvention.

Drainbow is the Austin, Texas one-man vehicle of multi-instrumentalist Nicholas Sarcophagus, who writes, performs and records everything himself. Its debut full-length 'The Tower of Flints' (2020) careens between thrash riffing, doom weight, gothic atmosphere, jazz-tinged lounge interludes and ambient post-metal passages inside a single kaleidoscopic record. It occupies the DIY, one-person-band corner of the avant-garde metal scene, prioritizing eclectic mood-shifting over any single subgenre identity.

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.

Age of Silence is a Norwegian avant-garde progressive metal 'supergroup' formed in Oslo in 2004 by keyboardist Andy Winter of Winds, drawing members from Mayhem, Arcturus, The Kovenant, and Solefald. Their sole album, Acceleration (2004, The End Records), pairs 'aggressive guitar grind' with Winter's gothic, classically-tinged piano and synths, occasionally veering into pure electronic beats, per a Sputnikmusic review. A follow-up EP, Complications – Trilogy of Intricacy (2005), preceded a long hiatus for the project.

Eigenstate Zero is the solo project of Stockholm metal veteran Christian Ludvigsson, launched in 2018 to fuse progressive death metal with Frank Zappa-style jazz-fusion excess. Across Sensory Deception, Machinery of Night, The Malthusian and Shape of God Thought of Sun, Ludvigsson stacks odd time signatures and weird electronic/synth textures over a death-metal chassis, filling 'passages of eclectic weirdness' between the heavy sections.

Atrox is a long-running Norwegian avant-garde metal band from Trondheim (formed 1988, debut album 1997) that brands its sound 'schizo/psycho metal' — experimental, progressive metal built on sharp contrasts of light and dark, unorthodox structures, and intense, bizarre vocals. Rooted in an atmospheric death/doom origin, later albums on Season of Mist (Contentum, Terrestrials, Binocular, Monocle) push toward melodic yet unpredictable, keyboard-and-sample-textured territory in the vein of Arcturus and Manes. The band's guitar core (viNd and Rune Sørgård) has anchored it since 1997.

Kekal is an Indonesian avant-garde/experimental act formed in Jakarta in 1995, one of the first Southeast Asian extreme-metal bands to reach an international audience. Beginning in black/death metal, they transformed across their discography into a genre-collapsing project spanning progressive metal, jazz fusion, trip-hop, electronic/IDM, ambient and post-rock — the 2003 breakthrough 1000 Thoughts of Violence being the pivot. Since August 2009 the band has operated as a 'memberless' collective, with former members and volunteer contributors assembling new albums.
