Charlie Parker Complete Verve

The first popular jazz singer to move audiences with the intense, personal feeling of classic blues, Billie Holiday changed the art of American pop vocals forever. More than a half-century after her death, it's difficult to believe that prior to her emergence, jazz and pop singers were tied to the Tin Pan Alley tradition and rarely personalized their songs; only blues singers like Bessie Smith and Ma Rainey actually gave the impression they had lived through what they were singing.

The effects of the bebop revolution in jazz music are still being felt and explored. Of the half dozen true pioneers of the movement, pianist Bud Powell has remained somewhat in the shadows, although his work has become a major touchstone for true devotees of the music and a principal influence for most of jazz’s most explorative pianists.
