When I was a kid, I wrote music - from the age of 11 until the age of 18.

I didn't have a record player.

I think there are influences that you open the door to, and influences that come under the door.

I'm not a music lover in the sense that I look for something to have on. I've never had that attitude to music.

I don't have ideas so much as there are things which constantly evolve... there are various threads or layers, if you like, which change.

The piece that had a large influence on me was Turangalila.

The theatre only knows what it's doing next week, not like the opera, where they say: 'What are we going to do in five years' time?' A completely different attitude.
