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.

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.

I have a big barn that I converted to my music studio, so I go there early in the morning and the first thing I do is rowing. And that's when I listen to a lot of 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.

A piano is a machine, but you've got ivory and there's weight behind the keys and you have this really - you feel the resonance in the instrument, you feel the vibration in the pedal. I mean, these a still very crude.

I'd studied piano first and switched over to cello when I was about seven. I played mostly chamber and solo classical music. I got really involved with rock music when I was a teenager. I wired up my cello.

I think that one of the things about music is it's supposed to be spontaneous, it's supposed to be real human beings bouncing off of each other whether its from the stage or to the audience, or jamming with friends.
