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.
