Weldon Leo "Jack" Teagarden was an American jazz trombonist and singer. According to critic Scott Yanow of Allmusic, Teagarden was the preeminent American jazz trombone player before the bebop era of the 1940s and "one of the best jazz singers too". Teagarden's early career was as a sideman with the likes of Paul Whiteman and lifelong friend Louis Armstrong.

Bebop or bop is a style of jazz developed in the early to mid-1940s in the United States. The style features compositions characterized by a fast tempo, complex chord progressions with rapid chord changes and numerous changes of key, instrumental virtuosity, and improvisation based on a combination of harmonic structure, the use of scales and occasional references to the melody.
Alto saxophonist Charlie Parker was a leading performer and composer of the bebop era. He is pictured here with Tommy Potter, Max Roach and Miles Davis at the Three Deuces club in New York City.
