who wrote the jazz classic i got rhythm
I Got Rhythm "I Got Rhythm" is a piece composed by George Gershwin with lyrics by Ira Gershwin and published in 1930, which became a jazz standard. Its chord progression, known as the "rhythm changes", is the foundation for many other popular jazz tunes such as Charlie Parker's and Dizzy Gillespie's bebop standard "Anthropology (Thrivin' on a Riff)".
Louis Jordan With his dynamic Tympany Five bands, Jordan mapped out the main parameters of the classic R&B, urban blues and early rock-and-roll genres with a series of highly influential 78-rpm discs released by Decca Records. These recordings presaged many of the styles of black popular music of the late 1940s, 1950s and 1960s and exerted a strong influence on many leading performers in these genres. Many of his records were produced by Milt Gabler, who went on to refine and develop the qualities of Jordan's recordings in his later production work with Bill Haley, including "Rock Around the Clock".
