Whenever newspapers write of the Great Voices of the Twentieth Century, Billie Holiday will be among them. She is among the finest ever interpreters of the popular song as well as being a great jazz vocalist. The rock musician, J.J. Cale described her appeal by saying, "Billie Holiday is probably the biggest exponent of laidback there is. She always sang behind the beat and I loved that." Just listen to the miraculous way Billie sings the standard The Very Thought Of You or songs from George Gershwin s Porgy And Bess.
