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 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 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 generation of composers that are just preceded me, people like [Karlheinz] Stockhausen, [Pierre] Boulez, and, well, [John] Cage for that matter,[Morton] Feldman ... That was a kind of experimental music that was very isolated. It had no real public.

Akhnaten is kind of a dark, kind of mysterious character. We don't know a lot about him - a lot of information on him was lost. But he obviously was a kind of iconoclast of him time. I guess I'm attracted to people like that. Like [Albert] Einstein also, who radically changed our way of thinking about the world we live in.

I think it's a great handicap to be discovered at an early age. I didn't have that burden of early success. I had the much more livable and durable career where success comes late, and comes slowly, and you ease into it. So by the time it comes, you're ready to deal with it.

What I've noticed is that people who love what they do, regardless of what that might be, tend to live longer.
