A popular music series curated by Luciano Berio, broadcast by RAI in 1972. In twelve episodes, Berio explores what "music" means in the contemporary world—from pop to jazz, from rock to electronic music, from classical music to the most radical experimentation—analyzing the protagonists, instruments, languages, society, and cultural context of sound in the late twentieth century. It is considered one of the most important popular music series ever produced in Italy.
