Known as "The Group" or "Il Gruppo," they released seven albums across the Deutsche Grammophon, RCA and Cramps labels: Gruppo di Improvvisazione Nuova Consonanza (1966), The Private Sea of Dreams (1967), Improvisationen (1968), The Feed-back (1970), Improvvisazioni a Formazioni Variate (1973), Nuova Consonanza (1975) and Musica su Schemi (1976).
Held in high regard in avant-garde music circles, they are considered to be the first experimental composers collective, their only peers being the British improvisation collective AMM.
