Puerto Rican composer Juan Tizol wrote “Caravan” in 1936, and the song was chosen by Duke Ellington to perform that same year. Here is Duke Ellington and his Orchestra in 1952, playing "Caravan" featuring Juan Tizol himself on trombone.
Tizol was a composer and trombonist who started out on violin. He's best known for his Latin influence on the Ellington band with songs like "Caravan" and "Perdido."
