Donaldson Toussaint L'Ouverture Byrd II (December 9, 1932 – February 4, 2013) was an American jazz and rhythm & blues trumpeter, composer 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.
