I don't think I'm capable of making radical changes, but over a period of four or five years you can perceive very big changes, and they seem rather small at the time.

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.

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

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.

Satyagraha is an opera which I wrote for the Netherlands Opera, so it uses an orchestra of around fifty, a chorus of forty, and there are about seven soloists. The opera ... Satyagraha means truthful, so it was a name [Mahatma] Gandhi used to describe his civil disobedience movement.

I think I'm really part of a whole generational movement in a way. I think a lot of other people since and during this time have gotten interested in writing what we can still call experimental music. It's not commercial music. And it's really a concert music, but a concert music for our time. And wanting to find the audience, because we've discovered the audience is really there. Those became really clear with Einstein on the Beach.

I travel the world, and I'm happy to say that America is still the great melting pot - maybe a chunky stew rather than a melting pot at this point, but you know what I mean.
