Walter Davis Jr. was an American bebop and hard bop pianist.

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.
