I don't know that I make a big distinction between the big pieces and the little pieces, because I don't experience them in that way. I mean, by the same token, you're out touring with a band and then you're writing string quartets, and in a funny way, isn't it all the same, in a way? It's all just music.

I shift between mediums very frequently. Instead of taking a break from writing, I just write in a different medium or in a different way or for a different purpose, so that I don't actually stop writing - I just go to something else. Like going from a big symphony to a piano piece is great and very refreshing, I find. And then going from that to a big concerto, and then having to go out and play.

But the difference between the little pieces and the big pieces - I'm not actually sure which are the little pieces. With some of the big pieces, it's a lot of musical running around, whereas the little pieces, you can say everything you want to say.

A new language requires a new technique. If what you're saying doesn't require a new language, then what you're saying probably isn't new.

It takes about a year to write an opera for me, but not a really a year of writing. I'm touring at the same time, and I'm playing, sometimes doing smaller projects.[The opera] Akhnaten fits in with Gandhi and Einstein, so that forms a trilogy in a way.I picked people who were these kind of larger than life characters, who kind of changed the world they lived in by almost the force of their personality and their inventiveness. People that I think not only do I admire but I think they're admirable people.

I think I'm really part of a whole generational movement in a way. I think a lot of other people since and during this time have gotten interested in writing what we can still call experimental music. It's not commercial music. And it's really a concert music, but a concert music for our time. And wanting to find the audience, because we've discovered the audience is really there. Those became really clear with Einstein on the Beach.

I'd say it's just part of the world that we live in; it's part of the music world.
