A really cool find! This is a vinyl pressing of Grateful Dead Hour #42 with high-quality soundboard recordings from the band's 1972 New Year's Eve show. It comes in a generic sleeve with the original program notes. For the first year of the GD Hour radio show, these were pressed up on vinyl and sent to the participating stations to play on air, which means it even has the very '80s commercials and the intro by host David Gans right on the record. (The ads they thought would speak to Deadheads is a true highlight here.) According to an old interview with Gans, they only pressed up about 100 of these per show, which means your limited Record Store Day Dead albums have nothing on the rarity of this one!
Side one has great versions of Brown-Eyed Women, Box Of Rain, Don't Ease Me In, Beat It On Down The Line and Sugar Magnolia, while side two has that night's legendary version of Truckin' that clocks in at around 24 minutes and destroys everything in its path. You can find all this music online these days, but as someone who grew up tuning in to this show religiously on Sunday nights I was besides myself when I found a stack of these.
Play notes: Quiet vinyl. Program sheet has wear as shown.
