Sometimes I intentionally cut it off. I just want to be in silence, especially when I'm traveling. I watch movies without sound.

It's a very simple process. He [Danny Boyl] comes in the tube (subway) and then he sits with me for 3 hours every evening and then I work on something. Then later, if he likes something, I put it even more perfectly. I tweak stuff. So this happened for 3 or 4 weeks and the music was done.

I wanted to be part of something bigger

I didn't see it coming at all. I just wanted to have this new experience with this team of Danny Boyle, Christian (Colson) and Simon (Beaufoy). It was like an excursion for me from my normal routine and the Indian movies I do and that helped.

I played a couple of ideas and then had this unusual texture underneath which was like this little granulated kind of pipe organ almost like a scratchy record which he started [inaudible] brilliantly. "Oh I love that song." And when things go fine, it's good. So he started loving that song and that song was used quite a lot in the movie which is very granulated stuff on the guitar.

Since I worked with Danny Boyle before on Slumdog Millionaire, we have great success and everything. So, when I first got the script and the screenplay of Simon (Beaufoy) and I was reading it, even before the shoot, some kind of sounds came into my mind and I put some stuff [down] and sent it to Danny when he was cutting the movie.
