Didn't walk out before but did walk out on a Dylan concert. The Dawes opened and were excellent. Like an idiot I paid $200 to one of those resellers online only to get to a half-full Civic Center selling tickets at the gate for $20. Honestly, I could barely figure out what song was being played. Dylan changed chords and tempos and garbled his way through the 5 songs we stayed for, it was horrible! Of course the folks next to my wife and I were like cultists and explained "we just don't get Dylan", lol. What I do get, some acts need to stay off the tour circuit and remain in the studio. By the way, I still consider Dylan one of the greatest poets, songwriters of all time.
