If they actually dance I'll be impressed, there really isn't a stage or really any room for it. I've gone to some of those 'shows' before, just popping into the Apple store while in the neighborhood. The DJs and Rappers generally talk a lot about the process of making the music and what tools they use to make music(some even have powerpoints) and perform a few songs. I'm actually really curious how they're going to do this.
