Music in movies is all about dissonance and consonance, tension and release.

Music is like a huge release of tension.

That will always be my music, man. I play 'Kind of Blue' every day -- it's my orange juice. It still sounds like it was made yesterday.

If architecture is frozen music then music must be liquid architecture.

I guess hip-hop has been closer to the pulse of the streets than any music we've had in a long time. It's sociology as well as music, which is in keeping with the tradition of black music in America.

I only hope that one day, America will recognize what the rest of the world already has known, that our indigenous music - gospel, blues, jazz and R&B - is the heart and soul of all popular music; and that we cannot afford to let this legacy slip into obscurity, I'm telling you.
