Leroy Eliot "Slam" Stewart (September 21, 1914 – December 10, 1987)[1] was an American jazz double-bass player whose trademark style was his ability to bow the bass (arco) and simultaneously hum or sing an octave higher. He was a violinist before switching to bass at the age of 20.
This sample highlights Slam Stewart's style of bowing and simultaneously singing/humming one octave higher. Stewart's solo picks up at the end of a Charlie Parker saxophone solo and leads into a trumpet solo by Dizzy Gillespie.
