These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Awesome Music: An awful lot of it, given the band's Long Runner status. American Beauty is usually cited as the band's studio Magnum Opus, with Workingman's Dead being a close second. As for the band's live output, fan opinions are divided (as would be expected with a band that toured as long and was as thoroughly documented as the Dead; the band played some 2,350 shows), but frequently cited contenders for Best Show Ever include:
February 13 & 14, 1970 at Fillmore East, New York, NY (parts of these were released on Dick's Picks Vol. 4 and Bear's Choice; the 13th is usually cited as the superior show due to the half-hour-each versions of "Dark Star" -> "That's It for the Other One" -> "Turn on Your Love Light")
May 2, 1970 at Harpur College, SUNY, Binghamton, NY (almost the entire performance was released as Dick's Picks Vol. 8, but the electric set is unfortunately in mono)
August 27, 1972 at Old Renaissance Faire Grounds, Veneta, OR
May 8, 1977 at Barton Hall, Cornell University, Ithaca, NY (compounding this show's reputation is the fact that it was the first A+-quality soundboard bootleg many fans heard, but it's still a very good performance from one of the band's best years)
Face of the Band: Jerry Garcia, no matter how much he insisted that he wasn't. In fact, after Garcia died, the remaining bandmates toured a few times as The Other Ones before changing their name to "The Dead".
Newbie Boom: "Touch Heads", the fandom name for those who became fans of the band because of the success of "Touch of Grey" in the late 80's.
