"This is Haynes' first time as a feature-length documentarian, and his approach is just as surprisingly conventional as it is predictably outré."
★★★★ Stephen Garrett, The Observer

"Haynes presents the evidence on an ever-shifting split screen, generating a kind of live artistic friction as the clips and images play out side by side."
★★★★ Robbie Collin, Daily Telegraph 

"This is a great documentary about people who are serious about music and serious also about art, and what it means to live as an artist."
★★★★ Peter Bradshaw, Guardian
