"I was 11 when this film came out and it was the first time I ever went to see a film twice in one week. It blew me away and changed my life. Not just the film, but largely [György] Ligeti's atonal choral pieces. This discordant, sometimes beautiful, intertwining of voices, that were dark and then beautiful and then disturbing and then uplifting. I went out and bought the album, and then put it on my record player in my room and shut myself in my wardrobe with a flashing light and spent hours in there. I wanted to shut myself off from the world and immerse myself completely in this extraordinary sound. And I went on to be an artist that built environments and quadrophonic sound spaces – purely based on this experience. And years later, when we came to write the score for Danny Boyle’s Sunshine, I said, "do you think 2001 can be referenced?" and Danny said, "absolutely", and that was just like heaven for me. This album is at the core of where my head’s at. One minute it will be playing some Brahms and then it’s playing this beautiful, yet discordant, choral music and I think like that now. This is the rhythm of my bones. Something for the future is to score for a choir."

"I'd been into music for as long as I can remember, from being four years old. My dad bought me a record player when I was 11, and I went out and bought three albums: I had those Beatles double albums, the red and the blue, '62-'66 and '66-'70, I bought those, and I also bought Sticky Fingers by the Rolling Stones. That was the first Stones album that I bought. I actually wore it out, and parts of it became unplayable, even with halfpenny pieces on top of the stylus. For me, the Stones, when they pulled away from the Beatles' influence and became their own thing, it started with Beggars Banquet. It's those four albums - Beggars Banquet, Let It Bleed, Exile and Sticky Fingers, I think are the greatest years of the Rolling Stones as an individual, this is what we do, we're not following the Beatles any more. And they did it with such glory that I could easily have chosen [another] one of those four albums for the same reason. Once again we seem to be talking about unsung heroes, one of the great things about those Stones albums is the brilliant engineering by Glyn Johns; I think Andy Johns was involved as well, but the engineering on those records is just awesome, awesome, awesome."
