I saw the Cure at Red Rocks Amphitheater in Denver in May. I really enjoyed the show, and it was completely sold out. If you ever get a chance to see a show there, DO IT.
As far as Plex's comment about not many shows being worth $80 to see, I disagree. I paid much more than that to see the Cure and would do the same for other bands or other forms of entertainment I like, such as good seats at my favorite team's stadiums.
