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.

What came to me as a revelation was the use of rhythm in developing an overall structure in music.

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.

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 don't know what I'm doing and it's the not knowing that makes it interesting.

I've been working in theater, really, since about 1965. I started working with the Mabou Mines about then, and in a way I've always worked in the theater, but it's never been a main part of my work. And it wasn't until Einstein that I kind of shifted into high gear with theater, working with Bob, with Bob Wilson. And since then I find it a very attractive form to work in. It's just an extension of my work.
