As one of the most significant jazz pianists of the history of the genre, Herbie Hancock's contributions to music over 50 plus years of activity as a musician are nothing less than remarkable. Born in 1940, Hancock made history as a member of the Miles Davis Quintet of the 1960s. Hancock was also one of the most in-demand pianists of the decade. Important contributions to the birth of jazz-rock in the In A Silent Way/Bitches Brew sessions followed.
