George Wallington was an American jazz pianist and composer. Born in Sicily, his career as a pianist began in the early 1940s, when he played with Dizzy Gillespie and Charlie Parker and contributed to the development of bebop. Following several years as a sideman during the late 1940s, he formed his own group, experimenting with trios and a string ensemble before settling upon a permanent quintet.

Donaldson Toussaint L'Ouverture Byrd II was an American jazz and rhythm & blues trumpeter and vocalist. A sideman for many other jazz musicians of his generation, Byrd was one of the few hard bop musicians who successfully explored funk and soul while remaining a jazz artist. As a bandleader, Byrd was an influence on the early career of Herbie Hancock and many others.
