Check the website below for Phoenix area shows, it's the most comprehensive/accurate site I've found for the Phoenix area. I think it's run by Stinkweeds or associated with them: http://silverplatter.info/
Has anyone seen a rotating-stage show there? I saw the stage move for the Go Go's/Berlin back in the early aughts.
I have seen a couple of Roger Clyne and the Peacemakers shows there "in the round" as they call it. It works realy well in my opinion. Much better than an arena show that sells tickets on the side or behind the stage.
