San Francisco-born drummer Jerry Granelli was a fixture on the Bay Area hard bop scene plus did psychedelic sessions for such luminaries as Sly Stone in the ‘60s. He and bassist Fred Marshall formed the Vince Guaraldi Trio’s rhythm section. In 1965, pianist Guaraldi was commissioned to write the music for an animated half-hour Christmas special featuring characters from Charles M. Schulz’s Peanuts.

A Charlie Brown Christmas went on to become a triple-platinum holiday classic that still ranks in the top Christmas album sales over five decades later. Pretty impressive for a session that the Halifax-based Granelli recalls as being “counted down by the clock.” The sole, surviving member of the original recording group, Granelli with bassist Simon Fisk and pianist Chris Gestrin revisit the now legendary session. They’ll again be joined by a charming local children’s choir.
