Sometime it seems to my eye that they play and then move and then play and then move. Granted Bell and Marcus play very well. It just seems to me that it's hard to play and move and the same time, especially if you are playing much more complex music. All I can really remember from Bell's show is the little girl humming and the big yellow thing. If some one asked me about their music, I would be able to tell them anything about it. Maybe I'm just old fashioned.
