At TED, we’ve had the great privilege to watch Herbie Hancock improvise: Both solo and with others, like pianist Makoto Ozone. Now a new documentary exposes the jazz legend’s creative process: tracing the dozen or so collaborations behind his latest album, with behind-the-scenes footage and interviews. Anyone with an interest in creativity or collaboration will find themselves fascinated. If you’re a jazz fan, better yet.

Among the other well-known musicians — Paul Simon, Sting, Damien Rice, Annie Lennox, Carlos Santana — is relative newcomer Raul Midon, a blind singer/songwriter whose “voice trumpet” elicited murmurs of amazement both on-screen and off. New York-based TEDsters are in luck: You can catch Midon at next month’s TED event at Joe’s Pub.

Herbie Hancock: Possibilities” opened last week in New York and LA only; for those in other cities: the DVD is on sale.
