Fabulae Dramatis

Frore 5 Four is an instrumental avant-garde/progressive metal project from Canada, releasing a run of Bandcamp albums built around unusually prominent accordion. Reviewers describe the sound as 'stomping accordion polka weirdness juxtaposed to neoclassical harmonies' — vocal-free, structurally unpredictable, tonally caught between creepy and jovial.

System of a Down are an Armenian-American alternative-metal band from Los Angeles, formed in 1994, whose sound welds thrash aggression to Armenian folk melodies, abrupt tempo shifts and Serj Tankian's operatic, politically charged vocals. Multi-platinum records like Toxicity (2001) and the Mezmerize/Hypnotize pair made them one of the era's biggest metal acts. In 2008 Tankian co-wrote and traded vocals with Mike Patton on 'Bird's Eye' for the Body of Lies soundtrack.

Acrylazea is a Rochester, NY avant-garde/progressive metal act (formed 2016) built around an interstellar-pirate concept, complete with invented stage personas (The Captain, Sirius J. Axion, The Eye, Professor V.V. Olfenstein, Byron Nova). Debut A Cavalcade of Cosmic Calamity (2021) fuses melodic death metal, folk metal, power metal and neoclassical shred, with guest vocals from Judas Priest's Tim "Ripper" Owens. Reviewers place it in the theatrical/conceptual-metal lineage of Unexpect and Vulture Industries rather than any straightforward extreme-metal subgenre.

God of Shamisen is a Santa Cruz, California band formed in late 2004 and led by Tsugaru-shamisen player Kevin Kmetz, billed as the world's first rock band to combine metal, funk, and progressive rock with the Tsugaru-shamisen, a fretless lute from Northern Japan. Its lineup features Kevin Kmetz (shamisen), Lee Smith (drums), Karl Schnaitter (guitar), and Mark Thornton (bass). The band shares members with experimental band Estradasphere: drummer Lee Smith moved to Santa Cruz in 2004 to join Estradasphere as their permanent drummer, and Kmetz also worked with the group. Their second album, Smoke Monster Attack (2010), was produced by Billy Anderson and Mark Thornton.

Faun Fables is an American avant-folk / dark-folk band based in Oakland, California, formed in the late 1990s by Spokane-raised singer, dancer and songwriter Dawn McCarthy. Known for a theatrical "songtelling" style, the band blends British, Scandinavian, Appalachian and Eastern European folk traditions with art rock and performance art. McCarthy's principal collaborator is Nils Frykdahl of Sleepytime Gorilla Museum, whom she married; the two build the project around McCarthy's voice and Frykdahl's multi-instrumental work.

Rabbit Rabbit Radio is the song-a-month art-pop duo of Carla Kihlstedt and Matthias Bossi, both formerly of Sleepytime Gorilla Museum. Founded in February 2012, the project releases a new song to Bandcamp subscribers on the first day of every month, collecting them into yearly volume albums. Drawing on art song, folk song, industrial and improvised music and heart-wrenching balladry, their songs are described as raw, beautiful, sparse and rich. The core duo is expanded in performance and recording by Jeremy Flower and Jon Evans.

Polkadot Cadaver is an American avant-garde/alternative metal band formed in Rockville, Maryland in 2007 by ex-members of Dog Fashion Disco, and stylistically a close continuation of that band. Their 'schizophrenic musical madness' shape-shifts between thrashing metal, folk-pop, experimental rock and darkly comedic theatricality across albums like Purgatory Dance Party, Sex Offender and Echoes Across the Hellscape. Clutch's Neil Fallon guested on their 2013 record.

Angizia is an Austrian avant-garde/gothic metal act founded in Vienna in 1994 by Michael Haas (Engelke), built around theatrical, operetta-influenced concept albums often likened to a traveling circus or puppet theater. Their catalog, including the 'Russian trilogy' of Das Tagebuch der Hanna Anikin, Das Schachbrett des Trommelbuben Zacharias and 39 Jahre für den Leierkastenmann, fuses Central European folk and classical operetta with gothic/black metal texture. They have released on Napalm Records and Black Rose Productions.

Nucleus Torn was a Swiss avant-folk/progressive-metal project founded in 1997 by multi-instrumentalist Fredy Schnyder, expanding into a chamber-metal ensemble with cello, violin, flute, and an array of folk instruments (hammered dulcimer, bouzouki, oud, bagpipes). Signed to Prophecy Productions from 2006, the band moved between folk-rock, 1970s progressive-rock homage, and extreme metal across a decade-plus discography, including a conceptual Nihil/Knell/Andromeda Awaiting trilogy. Active until 2015, the later lineup included Eluveitie's Anna Murphy.

A British folk-metal band formed in 2019 around guitarist/vocalist/flautist Joe Parrish-James (Jethro Tull, 2020-2024), built explicitly on 'the preservation and exposure of traditional folk music... presented through the modern medium of metal and rock.' Their Pryderi EP (2021) traces a character from the Welsh Mabinogion across four movements blending Celtic/medieval-folk instrumentation with progressive-metal frameworks, and the debut LP Lakesongs of Elbid (2024) expands that fusion across 12 tracks. Live sets reportedly splice Black Sabbath riffs into flute arrangements, underlining the band's folk-instrumentation-over-metal-riffing identity.
