When I was done with high school, I knew that music was really important to me and I knew I didn't want to be a cellist, but I wasn't really sure if I wanted to be a composer, or think about - I was just interested in the ideas behind music, I was interested in mathematics.

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

I love working with technology because it allows me to follow my imagination and to invent new things.

I like the idea of imagining a sound and feeling a sound and then having it come out through your body, through an instrument. That's an important way to make music.

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.

Perhaps 25 to 50 years from now, I can design a piece of music, no so that it appeals to something common in millions of people, but I can design the music so that it's exactly right for you and only you at this particular moment for your particular experience, things that have happened to you over 20 years, to you're particular mental state right now.

The one obvious thing is that the devices are so good now that you can also see their limitations extremely well.
