Corrosion In The Pink Room: Spectacular, little-known Pink Floyd performance, 1970

Pink Floyd performing an avant garde instrumental—sometimes bootlegs title the number “Corrosion,” other times it’s called “Corrosion In The Pink Room”—on a sound-stage without an audience. It segues into “Embryo” with snatches of “Heartbeat Pigmeat” and “Several Species of Small Furry Animals Gathered Together in a Cave and Grooving With a Pict” along the way.

Originally broadcast ORTF1 in France, January 2, 1971 (filmed the month prior) as part of a TV special featuring the work of celebrated dance choreographer, and frequent Pink Floyd collaborator, Roland Petit.
