Between June 26 and 29, 1976, the sixth edition of the Festival of the Juvenile Proletariat took place at Parco Lambro in Milan, an event conceived by the countercultural magazine Re Nudo. The organizers invited Alberto Grifi to film those days filled with meetings, debates, and concerts, but not everything went as planned. This is the 58-minute version (from 27 hours of footage) edited by Grifi himself after the event.
