I first bought this LP (yes, LP) when I found it in a dusty used album bin, about 2 blocks from Fantasy Records in Berkeley where it was recorded. The album was in perfect condition, so I made a tape copy that got played year after year. Eventually I wore the tape out, so I took out my pristine album and made another copy. No one I knew had the LP or knew where to find it, so they'd ask me to make them a tape. I wouldn't copy the LP directly - it was priceless to me - though I'd lend out the tape for them to copy. Eventually someone never returned it, so I made yet another copy from the LP. I wore that one out too, but by then they'd issued the CD and I bought that. The CD had one or two tracks the LP didn't have, and to be honest they added little for me - the LP as it stood was perfect. A few years later a bunch of my CDs were stolen, so I bought it again, which is my current copy.
There really isn't any more to be said about this CD. Everyone's seen the show, and the music of Vince Guaraldi is timeless. One of the all-time greatest jazz musicians, Guaraldi had a unique and almost universally liked style few, if any, modern musicians can touch. The soundtrack has taken on a life of its own - play it at a party and people will smile and relax as they are almost subconsciously transported back to childhood.
The Christmas season starts for me right after Thanksgiving, when I first play "A Charlie Brown Christmas". Through all the hassles of traffic, shopping, cooking, cleaning, and the overall holiday rush, this CD always reminds me of the true meaning of Christmas, what this season is truly about. And I still take out and admire securely-stored LP version which I will never give up.
