I, as a young guy getting out of music school, I didn't like the prospect of spending my life writing music for about 200 people.

If you remember your lineage, you will never feel lonely.

I shift between mediums very frequently. Instead of taking a break from writing, I just write in a different medium or in a different way or for a different purpose, so that I don't actually stop writing - I just go to something else. Like going from a big symphony to a piano piece is great and very refreshing, I find. And then going from that to a big concerto, and then having to go out and play.

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.

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 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.

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