An odd find,for sure. This is a 16 minute short film made in 1968 that features Hundreds of fast clips of "A Day in the Life of San Francisco". Some people claim this film was shot by Syd Barrett,who was the original founder of Pink Floyd before he receeded into oblivion around early to mid 70's,depending on his altering state. This seems unlikely,however Pink Floyd scored it's soundtrack in October of 1966 before their first official album was even released and Syd was still very much part of the band,in fact,they had just renamed themselves "Pink Floyd",they were once the called the "Architectural Abdabs" along with many other names.
Highly recommended to any Floyd fan because the soundtrack is one of the earliest Floyd recordings to survive. It is a 15 minute version of "Interstellar Overdrive" an early Floyd classic that was to remain in their set lists until around 1971. I believe it is a one-take demo recording,therefore the sound quality is a bit rough but if you can find a good copy,it still sounds better than most of the bootleg releases of the song only.
Like I said,tons of fast clips. Makes the editing in "Natural born Killers" look like Hitchcock's "Rope" so it might induce a bit of nausea!
