This is amazing! A completely unreleased work recorded in 1973 at the legendary club
in Rome, Italy! An experimental vocalization group that was also popular for its reissue release by . A night of musicians who are inevitable in telling the lifeline of the Italian underground avant-garde, such as Roberto Laneri, one of the founding members of Prima Materia, Alvin Curran, an American genius musician, and Giancarlo Schiaffini, an avant-garde trombone specialist. A rainy day excavation sound source by the limited all-star ensemble! An illusion of members of a legendary group that appeared in the late 1960s and 1970s, such as the prestigious Gruppo di improvvisazione Nuova Consonanza and Musica Elettronica Viva, and who became the world's leading avant-garde music based in Italy. Archive has appeared for the first time in about 50 years. I am impressed with the creative and avant-garde sounds that transcend categories and boundaries. Includes gorgeous liner notes and photos. This is just a historical document.
