condition (record/cover): NM / VG- (repaired 3" rip and sticjer removal residue on front, general wear) Released in 1969 on Deutsche Grammophon, Improvisationen is widely regarded as a masterpiece of avant-garde free improvisation. It documents the peak of the Gruppo di Improvvisazione Nuova Consonanza (GINC), a collective of composers who rejected traditional musical systems in favor of noise, anti-musical structures, and collective spontaneity. Critics and historians describe the album as a rigorous exercise in "New Music" that blurs the lines between classical training and radical experimentation: The tracks utilize extended techniques on classical instruments (like prepared piano and trumpet) alongside early electronic sounds and tape music. Unlike their later, more "cinematic" work (like The Feed-Back), Improvisationen is strictly experimental. It features the core line-up of Franco Evangelisti, Ennio Morricone, Egisto Macchi, and others. The group frequently debated their approach to dynamics, often performing "counter-dynamically" to subvert listener expectations.
