Rick Rubin

Usually when I start a new project there's a fear of the unknown; maybe it's a band I've never been in the studio with before. People are so different. It's almost like you need to go through the process, discover and unlock what it is that makes that band that band. And a lot of times they don't know it.

I've always been an outsider. When I did magic, I was the only kid. When I worked with Johnny Cash, I was completely out of place in Nashville. And when I started Def Jam, I was the only white guy in the hip-hop world.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.
