I think the seed was planted when I was a teenager, and it took me until I got out of Juilliard. At Juilliard I was just learning to be a composer, but I was also learning how to manipulate computers.

I almost never these days sit down with a CD or my laptop and just listen to a piece with a score. I probably would do that while I'm exercising.

I think it's maybe because Sergeant Pepper's came out when I was about 13 or 14 and that was a pretty impressionable age, and it was such a kind of radical period. But that period of the Beatles really had a big influence on me and I think are directly related to hyperinstruments.

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.

Music seems to stimulate more parts of our mind than almost every other activity. It combines more parts of our minds. It synchronizes our minds. It allows people in groups to do a non-verbal immediate activity together.

The way I listen to music goes in waves depending on a lot of things. How busy I am, if I'm in between composition projects, if I'm starting a new project. So, the only time I listen to the radio for music is with my daughter's when I'm driving them to school, or driving them somewhere.

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