When Pink Floyd took the stage on their mid-1970s "Dark Side of the Moon" tour, they performed in front of a stunning video cut-up created by British animator Ian Emes. Above are screen projections from the 1974 French tour. Below, a reel from the 1975 North American tour. (The album audio was added by someone else later.) From Wikipedia:
Emes' first major work, 'French Windows', was started while he was subsequently a student at Birmingham College of Art and finished while he was unemployed. It was set to the Pink Floyd recording "One of These Days". After it was shown at Birmingham's Ikon Gallery, it was screened on the television programme The Old Grey Whistle Test, and thereby came to the attention of Pink Floyd. The band invited Emes to give them a private screening, and afterwards to make films to be projected during performances of The Dark Side of the Moon. His animation for their song "Time" is on Pink Floyd's Pulse DVD. He subsequently worked with Roger Waters, making live action film for his performance of The Wall – Live in Berlin.
As a result of his work for Pink Floyd, Linda McCartney asked Emes to animate Wings' "Oriental Nightfish". He has also made animations for concerts by Mike Oldfield, and directed The Chauffeur for Duran Duran.
