Assemblage of concert footage features Pink Floyd in concert playing  “Sheep”.  This song appeared on their release “Animals”.   The Pink Floyd concert experience was a mixed media event with film clips and visuals projected onto a massive screen, lasers, a light show, and huge props reflecting song subject matter.  Here we witness a very saturated color film of the performance and hear the rich aural textures of synthesizer (Richard Wright), processed guitar (David Gilmour), reverberating vocals (Roger Waters) and driving drumbeats (Nick Mason) intermixed.  Trippy to say the least.  Nice use of vocoder near the end of this clip.
