Hundred Year Hall, for sure a better choice than Europe 72. As a bit of a tangent, the official release of hundred year hall is only half the damn show (4/26/72). Luckily a sbd of the rest of the show (and almost all of the entire tour) is out there so you can splice it back together. Chinatown shuffle is a good reason to get some europe 72 shows. People have already summed this up enough. All you can really do with the dead is let and play and figure it out, its really like listening to a multiple bands that happen to play some of the same songs.
