If they're going the whole nostalgia tour route, I'd much prefer something like Tiny Music front to back, or Shangri La Dee Da front to back, but I imagine this move is strictly taking the 20 year anniversary of their most popular album and exploiting it for money. Whatever, smart move on their part I guess, but it isn't exactly for their hardcore fans.
When I saw them in 2008, and then again in 2010, I stood front and center both times and both times there was no interaction with the crowd at all. I was hoping for a high five at the very least... if there was a couple of things I'd demand for this next tour (to get me to even go), it would be to have a small scale acoustic set, and to feature guest musicians, and for the band to have a meet and greet for once, for God's sake.
That's the problem, though. This will only ever be wishful thinking. If there's anything this band is good at, it's keeping it's distance from the people that spend so much money on them. Quite honestly, after seeing them in 2010 I told myself to not even bother with another STP show.
