Oh yeah...
Eagles (last year) Much better in concert than on the albums. Or maybe it was sitting through 3 hours of it that finally made me like them sort of.

As for shows, not concerts (since Spiff opened that up) in Vegas last year, I saw
Blue Man Group-great show. Hard to describe.
Mystere (fantastic show)
O (another fantastic show, but Mystere was better)
Zumanity (good show, but it needs more work to get anywhere near the level of the other three)

I am the Doctor, and THIS... is my SPOON!
