This is a very good documentary about one of our outstanding living jazz pianists. Herbie Hancock, best know for his "Cantaloupe Island" and "Watermelon Man" nowadays ubiquitous classics, reveals in this film how versatile and adaptable a musician he is. We witness Hancock creating music pieces with the great like Sting, Annie Lennox, Santana and Angélique Kidjo but his most interesting experiments are pulled off with young, lesser known talents from Ireland and Santa Monica. Raul Midón had us rush to check him out after the performance. While the documentary focuses on the interaction of Hancock with living musicians, Miles Davis could not have been left out given his great influence on Hancock in the "second great quintet" years. After showing the portrait of a talented music experimentalist the documentary attempts, with less success, to show us the man delving in his own soul. It would have been better to show this side of Hancock throughout the film rather than treating the issue somehow separately towards the end.
