Hmmm....it was around $60 for decent tickets when Mark Knopfler came through town, but I don't think there's such a thing as a bad seat at Red Rocks, and the show was just amazing. I forget how much it was for Aerosmith (with Cheap Trick opening), but pricey. Generally, I like to pay in the neighborhood of $30 for a well-known act, $15-20 for a "cult following" national act, and generally no more than $7 for a local band.
