What I saw of this show was a phenomenal spectacle at every turn. Rihanna, who seems to have climbed to the very tip top of the musical heap, was gorgeous and the production, the dance, the staging was so visually exciting to watch and wonderful to hear. She's a star. She's got a prowl and a power that is unmistakable. Ke$ha who performed before her was a hilarious romp that can only be described as trailer park grunge and a wicked fun-loving chaotic delight. Ke$ha seemed to be having a wild time and so did everyone backing her up on stage including the dancers AND the musicians. She likes to bang on things and so she did at every chance she got! And Travie McCoy, who opened the night, took it all on without his regular bunch from Gym Class Heroes. His sound had more pop and I really enjoyed the little something different from him!
