Over my career, I'd say the last 25 years; we've gone from music and computer being for 10 people in the world to having personal computers, to now being able to do amazing things on your iPhone, or with Rock Band. So, right now there's enormous capability with technology in our devices that everybody has access to.

I've done a lot of operas. I've probably done more different kind of operas than anybody.

One of my interests in music has always been what it means, why it affects us the way it does.

I started realizing that one of the great things about opera is that if you make the right kind of story, you can still have this kind of abstract subliminal quality to take you on a journey, but you can root it just enough in a particular situation, a particular kind of real situation that a person might have, or a particular context in the real world.

Strangely, the thing I listen to 75% of the time, when I'm exercising with my headphones on is English Tudor/Elizabethan music, so music from about 1450 to the early 1600's.

I love Bach, I love Beethoven, I love Mozart, I love the Beatles, I love you know, Stockhausen, I love many things. But for some reason I come back to Elizabethan music because it's a little bit like the Beatles.

There were a lot of things happen in the mid-'80's that all of a sudden made it possible to do a lot of very quick interactive music.
