Frank Zappa was not only a groundbreaking musical genius, but also a filmmaker, Dadaist, philosopher, intellectual and above all – a particularly strong critic of the ills of American society. Thorsten Schütte's minimalist documentary is an intimate and fascinating encounter with the iconoclastic avant-garde artist, presented through a skillfully edited mix of archival footage – mainly interviews and long-forgotten concerts collected from three decades of artistic work – inviting us to delve into Zappa's musical world and outrageous mind. His music and ideas transcend generations and his anti-conformist message is more relevant than ever.
