Finally, ultimately, you write music for yourself. I mean, I need a public, I need people to play, I need everything else. I'm not working in isolation. But finally the man that writes the music is alone. And I have to respond to those criteria which are almost like inner needs or inner responses.

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.

I always knew what I wanted to do and I did it.

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.

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.

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

I find that people can’t find you. It’s kind of quiet. When I go to a city, I can almost always get a piano if I need one. So there’s something nice about being on the road and focusing on something you want to do.
