Earl Kenneth Hines, also known as Earl "Fatha" Hines, was an American jazz pianist and bandleader. He was one of the most influential figures in the development of jazz piano and, according to one source, "one of a small number of pianists whose playing shaped the history of jazz".

A big band or jazz orchestra is a type of musical ensemble of jazz music that usually consists of ten or more musicians with four sections: saxophones, trumpets, trombones, and a rhythm section. Big bands originated during the early 1910s and dominated jazz in the early 1940s when swing was most popular. The term "big band" is also used to describe a genre of music, although this was not the only style of music played by big bands.
