Winds

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.

One-man Vienna-based experimental progressive metal project helmed by David Angerer, whose 2026 album Palingenaeon plays like 'a film score at a party' -- neoclassical/symphonic prog metal stitched together with circus music, absurdist black comedy, and a loose concept about botched reincarnation. Extremely new and thinly documented outside a handful of prog/metal press write-ups.

Giant Robot was the short-lived mid-1990s trio built around guitarist Buckethead, drummer Bryan 'Brain' Mantia, and keyboardist/producer Pete Scaturro, releasing one self-titled album on the Japanese NTT label in 1996 before Brain's departure broke up the group. The record is a virtuosic, sample-strewn instrumental record splicing film dialogue into dense guitar shredding, with absurdist song titles signaling its jam-session, prank-prone character. It sits adjacent to Buckethead's vast solo catalog but stands as its own band credit -- distinct from the same-titled 1994 Sony Japan Buckethead SOLO album that shares its name and caused the scout's identity confusion.

Oh. is the solo moniker of Greek multi-instrumentalist, composer, and director Olivia Hadjiioannou, who writes, performs, records, and mixes every part of her music herself. Her instrumental progressive-metal EP Metallia (self-released, July 2018) is a six-part concept work built from layered electric/acoustic guitars, violin, keyboards, and shifting time signatures; its 'Red Lion' music video won Best Music Video at multiple festivals, including the French Riviera Film Festival in Cannes.

A Perfect Circle is an American rock supergroup formed in Los Angeles in 1999 by guitarist Billy Howerdel, a former guitar tech for Tool, Nine Inch Nails and the Smashing Pumpkins, and Tool vocalist Maynard James Keenan. Fronting a more melodic, art-rock-leaning counterpart to Tool, the band broke through with the platinum debut Mer de Noms (2000) and its David Fincher-directed single "Judith." The rotating lineup has drawn from across alternative rock, with Smashing Pumpkins guitarist James Iha, session drummer Josh Freese, and bassist Matt McJunkins among its long-running members. After a long hiatus the group returned with Eat the Elephant (2018).

Deli Creeps is guitarist Buckethead's formative avant-garde/funk-metal band, formed in Claremont/San Francisco in the early 1990s and built around Maximum Bob's manic vocals and Buckethead's already-virtuosic, genre-hopping lead guitar. Their sole album, Dawn of the Deli Creeps (2005), compiles re-recorded demo-era material and functions as an origin document for Buckethead's later solo vocabulary — several of its riffs and songs were repurposed on his solo records. Mike Patton has praised the band, and it sits at the root of the Bay Area Buckethead/Praxis/Primus-adjacent avant-metal cluster.

Real Loud is a New York sextet billed as an 'antiphonal chamber metal' ensemble, staging mirrored pairs of electric bass, guitar and drums across the stage for four commissioned premieres on its 2021 self-titled debut (New Focus Recordings). The record spans Meshuggah-inspired mixed-meter riffing, no-wave-tinged fervor and two more ambient, spatialized pieces built from ringing harmonics and hollow echo. It reads as contemporary-classical composers writing idiomatically for a metal band's instrumentation.

Bay Area funk-metal vehicle formed in 1993 by Primus drummer Tim 'Herb' Alexander during a break from that band, pairing his drums (and eventually lead vocals) with Tom Butler's guitar and Ian Varriale's Chapman Stick/Warr guitar. Two albums, Blacktongue (1994) and Motivator (1999, Rinse-N-Repent Records), trade on the same proggy, slap-and-stick alt-metal chops Alexander brought to Primus. A minor node whose interest for the atlas is almost entirely its direct Primus lineage rather than any genre-scrambling ambition of its own.

Dakrya are a theatrical/avant-garde metal band from Athens, Greece, founded in late 2004 by classically trained keyboardist Sophia Charalampous. Crime Scene (2010) was recorded in Sweden with producers known for work with Diablo Swing Orchestra and Dark Tranquillity.

Aberrant Vascular is a Helsinki, Finland project built in 2003 around opera vocalist Vladimir "Lumi" and keyboardist Heikki "Mr. Rych" Pöntinen, releasing a single album, Aegisthus (2012), that layers operatic vocal theatrics over trip-hop beats, industrial synths and guitar riffing. It has been namechecked alongside Arcturus, Solefald, Vulture Industries and Sleepytime Gorilla Museum for its bombastic, genre-blending approach, though reviewers note the metal riffing itself stays fairly conventional under the vocal pyrotechnics.
