Ever since its debut in 1965, the Vince Guaraldi Trio’s album A Charlie Brown Christmas has reigned as a Yuletide classic. The beloved Peanuts animated special from which it sprang was a sensation the first time it aired on CBS-TV, and so was its cool soundtrack by the veteran Bay Area pianist, which introduced countless children to the joys of jazz. Buoyed by annual airings of the program, the album has remained extremely popular ever since.
