Peter Whitehead’s most famous film is a free-form time capsule of Swinging London in 1967 which combines concert footage of Pink Floyd with “cameos” from a host of pop-culture icons: Mick Jagger, Michael Caine, Julie Christie, Lee Marvin, David Hockney, and Allen Ginsberg.

On one level, this rather raw documentary shows Whitehead to be a successor to the Free Cinema movement and a rare British exponent of cinema verité. However, it is just as fair to see him as the avant-garde, non-fiction flipside to Richard Lester. Both used pop-culture to chronicle the initial optimism and subsequent disillusionment of the decade, while at the same time creating the aesthetics of the music video.
