Fascinating, as always. I love this part:
"SONNY ROLLINS: Well, Jeffrey, improvisation is something which is highly misunderstood these days.
Improvisation -- I think my friend Branford Marsalis, saxophonist, he explained it very good. Improvisation is really not so much remembering things. And this is what I do when I play. I forget things. When I go on the stage, I want my mind to be a blank, so that I can -- things can come into me without my knowing where they came from.
JEFFREY BROWN: So are you surprised by what comes out?
SONNY ROLLINS: Sometimes, I'm surprised by what comes out, yes."
