Cal Tjader (July 16, 1925–May 5, 1982) was an American Latin jazz musician. Unlike other American jazz musicians who experimented with the music from Cuba, the Caribbean, and Latin America, he never abandoned it, performing it until his death. Tjader (pronounced "chay-der") primarily played the vibraphone. He was also accomplished on the drums, bongos, congas, timpani, and the piano. He worked with numerous musicians from several cultures. He is often linked to the development of Latin rock and acid jazz.
