For a white Viennese boy to write a tune that’s that black is pretty remarkable. He just captured the essence of the African-American heritage, just the statement of melody and feeling of that song. Clearly, in some past life, Joe must’ve been black.
– Herbie Hancock on “Mercy, Mercy, Mercy.”
I improvise music. Whatever you want to call it all, it is all improvised music. I may capture it and go back and write it down for others, but it was originally improvised.
