In order to arrive at a personal style, you have to have a technique to begin with.

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 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.

Theatrical times are different from concert times, to put it simply. Taking a figure like [Mahatma] Gandhi and setting him on a stage requires thinking about what theater is about and what the whole experience is about and what we're trying to communicate in that way, so you get into certain less abstract considerations.

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.

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

The work I've done is the work I know, and the work I do is the work I don't know. I don't know what I'm doing.
