You can't compare a concert to a sports event.  A concert does not have quarters, periods, innings -- a specific framework that takes the show to completion with a clear win or loss (or tie, regardless -- a measurable 'end'). 
  V.R. has 
one album out -- they're basically a new band, but they have a huge fan base dying to see them already (hence the price, which isn't outlandish, really, when you look at market demand) and they in fact did a favor by playing a smaller venue.   
 A lot of shows I see run about 60 minutes because they're newer bands with just one album out.  Sometimes they're phenomenal, sometimes not so much.  I don't understand this long list of requirements some folks have for shows.  Sure, if a band played 20 mintues I'd feel cheated, but that would be a pretty rare occurence.  But I'd also feel cheated by a band that played two hours or more and was lousy and disinterested.

 If I pay for a movie, I want a 90+ minute movie, not a 60 minute movie.
 
 If I pay for a four course meal, I want more than the entree.
 
 If I pay for a baseball game, I want 9 innings, not 6.
 
 If I paid for an NBA game, I'd want 4 quarters, not 3.
 
 If I paid for a hockey game (which I never would), I'd want three periods, not two.
