Herbie Hancock became a giant under the tutelage of giants. With Mwandishi and Headhunters, the former student then reared his own roster of jazz heavyweights. Unfortunately, at the height of his popularity and singular vision, Hancock didn’t get to work those forebears which shaped him into the iconoclast he was to become. Thanks to a Chicago radio recording from February 1977, we do have an opportunity to hear Hancock with another singular voice of his instrument–with both artists at the peak of their prowess. For this seemingly one-off performance Hancock teamed up with the king of the fretless electric bass, Jaco Pastorius.
