Franco Evangelisti was one of the founder members of Nuova Consonanza,and for sure one of the most radical composers of the Italian avant-garde. Evangelisti was a defendant of a rationalistic style of composing all his life, starting from the serialist school with its center in Cologne (Germany) in the fifties which saw its roots in the later works of Anton Webern. From the mid-fifties he immersed himself in hyperstructuralism, but almost from the start, there was a partly Cage-derived anarchic counterforce (namely indeterminacy) which sought to eat away the cultural edifice from within (Ordini, composed in 1955, is probably the first significant European work to incorporate an indeterminate pitch element). This force gets ever stronger in subsequent works, and in 1963 Evangelisti decided to abandon composition in favour of improvisation, and accordingly founded the composer/performer group Nuova Consonanza, whose early members included both Frederic Rzewski (keyboards) and the ‘Spaghetti Western’ film composer Ennio Morricone (trumpet). Some striking early examples of the group’s work (from 1967 onwards) can be heard on ed. RZ 1009.
