Vince Guaraldi’s music for “A Charlie Brown Christmas,” perhaps the most beloved of all holiday specials, is getting a surprising new multi-disc release thanks to the recent discovery of long-forgotten tape reels in the Fantasy Records vaults.

The 1965 “Charlie Brown Christmas” soundtrack ranks among the best-selling jazz albums of all time, having been recently certified 5-times platinum by the RIAA. It was the first of 15 TV specials scored by the San Francisco-based pianist, best known for his Grammy-winning 1962 instrumental “Cast Your Fate to the Wind.”

Most elaborate of the new Craft Recordings packages is the Super Deluxe Edition, consisting of a new stereo mix of the 11-track album and a remastering of the original 1965 version; three full discs of the original recording sessions from September and October 1965, in which Guaraldi, his drummer and bassist developed the various themes; and a fifth, high-resolution Blu-Ray audio disc.

It’s already out in digital form. The full physical package, including a 59-page hardcover book with extensive notes by Guaraldi biographer Derrick Bang, will be released on Dec. 2. The 2-LP, CD and digital Deluxe Edition, also out now, consists of the original 1965 album plus excerpts from the recording sessions. There is also a limited-edition Gold Foil version available on vinyl.

As for the music of other classic “Charlie Brown” specials discovered in the vaults, Mendelson says, “We found a lot of great stuff, including alternate versions and songs written for the shows that have never been heard. Stay tuned.”
