Callen Radcliffe Tjader Jr. was an American Latin Jazz musician, often described as the most successful non-Latino Latin musician. He explored other jazz idioms, especially small group modern jazz, even as he continued to perform music of Africa, the Caribbean and Latin America.

Vincent Anthony Guaraldi was an American jazz pianist best known for composing music for animated television adaptations of the Peanuts comic strip. His compositions for this series included their signature melody "Linus and Lucy" and the holiday standard "Christmas Time Is Here". Guaraldi is also known for his performances on piano as a member of Cal Tjader's 1950s ensembles and for his own solo career. Guaraldi's 1962 composition "Cast Your Fate to the Wind" became a radio hit and won a Grammy Award in 1963 for Best Original Jazz Composition. He died of a sudden and unexpected heart attack on February 6, 1976, at age 47, moments after concluding a nightclub performance in Menlo Park, California.
