Pink Floyd - Cluster One

"Cluster One", an instrumental, is the opening track on Pink Floyd's 1994 album, The Division Bell.
It is also the first Pink Floyd song credited to Wright/Gilmour since "Mudmen", from the 1972 album Obscured by Clouds.
It was never performed live by the band, though portions of it were included in the sound collage tape played before their 1994 concerts.
