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".

John Birks "Dizzy" Gillespie was an American jazz trumpeter, bandleader, composer, educator and singer. He was a trumpet virtuoso and improviser, building on the virtuosic style of Roy Eldridge but adding layers of harmonic and rhythmic complexity previously unheard in jazz. His combination of musicianship, showmanship, and wit made him a leading popularizer of the new music called bebop. His beret and horn-rimmed spectacles, scat singing, bent horn, pouched cheeks, and light-hearted personality have made him an enduring icon.
