Jazz Metal
Located in 2 routes
Genuine jazz harmony and improvisation welded to metal aggression: extended/altered chords, chromatic voice-leading, walking and fretless bass, swung or polyrhythmic feels and horn or vibraphone textures pushed through distorted guitars and blast-capable drums. Tempos lurch between metal velocity and loose fusion grooves; bass is often the lead melodic voice (fretless, Chapman Stick), drums favor ride-driven jazz phrasing and odd meters. Vocals range from death growls to clean croons or vocoder choirs, and arrangements prize sudden harmonic detours, dissonance and improvised solos over riff repetition.
History
Jazz Metal crystallized in early-'90s Florida death metal, where Atheist's Unquestionable Presence (1991) and Cynic's Focus (1993) injected fusion harmony, Latin rhythms and fretless bass (Tony Choy, Sean Malone) into extreme metal at Tampa's Morrisound studio. Pestilence's Spheres (1993) pushed guitar-synth fusion further. The lineage continued in Europe with Italy's Ephel Duath (The Painter's Palette, 2003), Norway's Shining (jazz-saxophone 'blackjazz'), and Germany's instrumental Panzerballett, who openly fused Meshuggah-grade metal with Zappa and Weather Report. The 2010s avant-garde wave — New York's Imperial Triumphant and France's Pryapisme — re-centered the style around dissonant brass, big-band textures and overt jazz pedigree, keeping it a small but influential corner of progressive metal.
