You know I usually have tickets somewhere in this list :) I haven't yet seen the Trans-Siberian Orchestra in person (and I think they've been on my list a couple times!) but this year I just saw a billboard for Cirque du Soleil coming to Joe Louis Arena in Detroit in February!
I have wanted to see one of the Cirque du Soleil shows since my girls' trip to Vegas way back in 2005. A bunch of the group I was with went, but I just couldn't afford a ticket since I was out of work right then (it was miraculous enough that I made it to Vegas!).
