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.

So the real drama for me is balancing live performances and writing, and one of the ways I balance it is I write in hotel rooms. That's not exactly balancing. Actually, writing in hotel rooms means that I'm refusing to deal with the problem.

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

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.

The hardest thing about traveling is that mostly you get to a point - and it always happens on every tour - where you can choose between eating and sleeping, but you can't do both.

I was a regular kind of academic music student. I was at Juilliard. I had to study all the contemporary music of the time, and changing that language very radically was just a sign or a signal that I was going to try to do something very different. I find that that's what I feel closest to. I found no real inner response in me in a non-tonal language.

I've been called a minimalist composer for more than 30 years, and while I've never really agreed with the description, I've gotten used to it.
