Kubrick wanted to use Atom Heart Mother Suite in 2001 but when Roger know that he wished decompose the music the band refuse.
He actually wanted to use it for
A Clockwork Orange and Kubrick probably returned the favor when he refused Roger's request to use audio of the HAL 9000 for his album
Amused To Death.
Incidentally you can see a copy of
Atom Heart Mother on the shelf behind the clerk as well as a copy of the
2001 soundtrack up front at the Chelsea Drug Store.
