Shot by Alberto Grifi at the Parco Lambro Juvenile Proletariat Festival between 26 and 29 June 1976. Grifi, together with Franco Berbero and a young Claudio Caligari, filmed 25 hours on video and 3 hours on film which never made it to the final cut of a report for which he had been called by the organizers, the editorial staff of the magazine 'Re Nudo'.
