I'll limit my comments on the tour but will add a bit about what this tour and the last might "do" for Mark:
1. Attending a show is a different experience from listening to a recording.
2. I can't comment on the earlier shows on the tour but the two later shows I attended showed a Bob in better voice than other shows in recent years - still raspy but getting behind the lyrics in an engaged way.
3. Mark, at the two shows I attended, did not vary much in either set list or performance and I enjoyed both. It was very welcome to hear some new songs live.
4. Some comments I read and/or heard about Mark said he lacked stage presence but, for me, this was an ensemble performance by all the guys on stage and Mark gave them as much space as the shorter set list allowed and I found this admirable. Had he cut the band members' contributions in favour of his own solos, perhaps the comments would not have been made but it would have been less palatable for me - maybe not for you.
5. Mark was both brave and absolutely right to concentrate on his recent work and not to trade on his DS reputation. Clearly, some members of the audience (not just Bob fans at that) had expected a "rock'n'roll" performance from him. Maybe this did mean he was more cautious in his own playing but I would suggest "more controlled and focussed" as appropriate adjectives. In contrast, Dylan did play a lot of his older "stuff" but these were in completely new arrangements and, may I suggest, this is perhaps what Mark may do in years to come - that is, play a few more DS songs but in radically new arrangements.
6. Also, despite playing a 15-song set most nights, Dylan played 57 different songs on the tour (excluding the nebulous opening instrumental). Since Mark's set was 10-songs long or thereabouts, he would have had to play 38 different songs to match that. Perhaps, again, that is something that he might attempt on future tours. I feel it would bring an additional edge to his performance, a step outside of his comfort zone. Of course, you lot (the "get-a-lifers" out there) would have to accept that the standard of performance might vary a bit from night to night but it would be a fair trade-off for a bit more variety, IMO.
There, I have kept it briefer than I might.
