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.

If you don't have a basis on which to make the choice, then you don't have a style at all. You have a series of accidents.

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.

My biggest problem about writing is whenever I write piano pieces, because I then have to learn to play them, which is sometimes not so easy.

I consider the first 20 performances just learning the piece. Think about it this way: If you think about a pianist who plays a Schubert sonata through his whole lifetime - if you listen to Rubenstein or Horowitz playing their repertoire later in their life, you understand the richness with which they play that music, and how differently they must have played it when they were younger.

The problem with listening, of course, is that we don't. There's too much noise going on in our heads, so we never hear anything. The inner conversation simply never stops. It can be our voice or whatever voices we want to supply, but it's a constant racket. In the same way we don't see, and in the same way we don't feel, we don't touch, we don't taste.

I like the idea that [Mahatma] Gandhi is appearing now in an opera hall in all these different places, and people kind of think about it again.
