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.

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.

I grew up on Bach and Beethoven and now I'm listening to more modern composers who I can't even name. But since I'm constantly doing music, it's difficult to have that quality time to listen to music and do classical stuff. That's the only reason I'm thinking of going on.

I've never watched Trainspotting. I just know it's a very critically acclaimed film. In fact, I've never watched any of Danny's movies [means before he met him]. I just worked with him and felt the energy of what he is about initially before I do something. In a way, I think that's why we have discovered each other rather than replicate something else.

Success comes to those who dedicate everything to their passion in life. To be successful, it is also very important to be humble and never let fame or money travel to your head.

Your best success comes after your greatest disapponitment

I basically love classical music. I love a lot of musicians playing together and the whole culture of that whether it's Indian or it's Western. But in India, I think it's limited to filler music unfortunately. That's one thing I want to push in India where we have the infrastructure of an orchestra where you play Indian melodies with an orchestra and something different for a universal audience. It requires a lot of work from me.
