More consciously experimental than Whitehead's other works, this film draws on a variety of sources, including sequences of London shot while Whitehead was at the Slade School of Art, glimpses of the singer and model Nico, and footage of the psychedelic underground nightclub UFO. There is also on-screen text, a voice critiquing it, and music from Pink Floyd, at this point still fronted by Syd Barrett--Whitehead's old painting friend from Cambridge. The track here, "Interstellar Overdrive", was recorded by Whitehead before the band signed to EMI and is much more exciting and beat-driven than the version they would later record for the label. There is no explicit link between the content of the film and the Cochrane Theatre, which is is named after, but the theatre was used as a venue for the Spontaneous Festival of Underground Films in 1966.

Shot by movie maestro Peter Whitehead,this film features rare full length performances from the classic late 60's Pink Floyd line-up at Sound Techniques London & material from the legendary '14 hour Technicolor Dream' extravaganza in April '67 at Alexandra Palace. The footage includes performance art by Yoko Ono and a Sgt. Pepper era John Lennon taking in the festivities(John and Yoko had not met then)
