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.

It's a wonderful profession, and it opens lots of doors, and I think it's quite right that people can accuse actors and actresses of being dilettante, but you learn on every job, whatever it is, the process moves you on in some way, and yeah, I want to expand my knowledge of our existence, I suppose.

Listen to the Beatles' 'Things We Said Today.' Ringo Starr does not play a fill in the entire song. It doesn't need it. 'A Day In the Life' has gorgeous fills, but there, the song needs it. When I play on any record, I'm striving to get where Ringo is. You play what doesn't take you out of the song.
