4/16/72 impressed me, 4/17/72 impressed me even more. The Dark Star is one for the ages, saying like a hundred or two separate things, but totally hanging together. Caution is another killer version, not quite as pulse-racing raunchy as the earlier ones, but still quite explicit, Pigpen working all night long, the sun rising on his sweating back.
4/21/72 is a dud. I remember liking it on the film, but here it really fell flat for me.
4/24/72 out of the gate with a very good Truckin', high energy out of the gate.
