I know some might consider this "too broad" or a "list question", but there are probably a very limited number of answers here.
I'm looking to explore Bruce Springsteen's illustrious touring career. I'm wondering what are the dates/titles of some of the "must have" ROIOs out there. Either spectacular performance, rare setlist, alternate lyrics or some other feature that makes you feel it would be a great primer for a new collector. Preferably from a SB/FM source, though better audience recordings are OK.
(For the uninitiated, "ROIO" stands for Recording Of Indeterminate Origin and is sort of the "politically correct" way of saying "bootleg")
