Considered the first collective of experimental composers, Gruppo D'Improvvisazione Nuova Consonanza formed in 1964 in Rome to chase the expressive potential of live improvisation to its furthest reaches. Led by Franco Evangelisti, Gruppo also included Ennio Morricone before he found fame composing soundtracks. The ensemble advanced the innovations of 20th century avant-garde in laboratory-like studio settings where the intuitive interplay between members flourished.
