Earl Rudolph "Bud" Powell (September 27, 1924 – July 31, 1966) was one of the most influential pianists in the history of jazz. Along with Charlie Parker and Dizzy Gillespie he was instrumental in the development of bebop, and his virtuosity as a pianist led many to call him "the Charlie Parker of the piano". Powell was perhaps the first pianist to vocalize on the piano, meaning that he transfered his vocalized improvisations directly through his hands to the instrument.
