Never knew about this before finding it on youtube today.
"Another lost Floyd release, very appropriately surreal psychedelic soundtrack for a surreal 60's indie film, the band never officially released this because they thought it would be a rip-off to sell "half of an album" at that time." It's damn good!
I read it was written by Syd Barrett and recorded the day after his last gig with the Floyd. The film is available on DVD. Released by Basho Records, July 2005 -
