When I'm at home, I just run all the time, you know; I get up, and I go pretty much four days a week outdoors. I go in the canyons around L.A., Malibu - just around L.A. there's a lot of different spots.

I have a trainer, a really nice woman named Nina Greenberg, and she got me a training plan, and we go running in the canyons in Malibu. It's just beautiful up there, absolutely gorgeous. You see bobcats up there sometimes.

I spend probably six months of the year working outdoors three or four days a week.

Music is made up out of these building blocks. Studying how these blocks go together and what they consist of and the math of how it works - it's all the same stuff; it's just different aesthetics that we're talking about.

I run about four to five miles, three days a week. I have four young children, so pretty much the only time I can get away is real early in the morning.

When you make music, you're forming these invisible vibrations in the air into different shapes and consistencies and speeds in order to create music, and understanding how the math of that works just gives you more colors to paint with, and allows you to get to what you want quicker.
