Just Listing to Jefferson Airplane 10-15-66 Early Show, the sound is great! One nit though, the write-up says "Just like the previous night's late show, the group's customary opening of a jet taking off roars through the PA system..."  Not this time, never happened, tape op missed his cue or something. Oh, and if I was picking the next concerts I would be looking for early King Crimson first... Then all those obscure bands that have mostly been forgotten.
