No disrespect to people that don't use music theory or don't know it. It does help to be able to figure out what key a song is in, even though with your scales you can figure it out so you can set your Auto-Tune right. So many songs with Auto-Tune are off or have the wrong note playing on the 808. And they pass it off as being hood.

I've always been fascinated with sound, since I was a little kid when my mother Dorothy Dean took me to my first piano lesson. Later on, my guitar, bass guitar, and synthesizer were my secret weapons.

Justin Vernon is one of the collaborators Kanye will always go to. He doesn't fit in with any genres - you never know if he's gonna sing, like, the Bee Gees or some crazy, distorted thing. And you don't know what he's saying half the time. He's kind of like Michael McDonald, like he's got marbles in his mouth.

One of my favorite moments was when me and Jay-Z made a song 'For Rhyme or Reason.' It ended up on 'Reasonable Doubt,' but they switched the beat because we couldn't get clearance from my label.

I used to play in biker bars, different places like that.

Willie D is one of the first people I worked with.

That's just what I call myself when I DJ: Mexican Wrestling Association.
