A piano is a machine, but you've got ivory and there's weight behind the keys and you have this really - you feel the resonance in the instrument, you feel the vibration in the pedal. I mean, these a still very crude.

I love Bach, I love Beethoven, I love Mozart, I love the Beatles, I love you know, Stockhausen, I love many things. But for some reason I come back to Elizabethan music because it's a little bit like the Beatles.

I think it's maybe because Sergeant Pepper's came out when I was about 13 or 14 and that was a pretty impressionable age, and it was such a kind of radical period. But that period of the Beatles really had a big influence on me and I think are directly related to hyperinstruments.

My message is to forget about dichotomies. The Brain Opera is an opera, even if it does not tell a story in the usual way. It is a psychological journey with voices - so I do consider it an opera.

I'd studied piano first and switched over to cello when I was about seven. I played mostly chamber and solo classical music. I got really involved with rock music when I was a teenager. I wired up my cello.

I almost never these days sit down with a CD or my laptop and just listen to a piece with a score. I probably would do that while I'm exercising.

Works of art should be stimulating. They should wake people up rather than acting like a sedative.
