Had the best parts of the Elevation stage
-crowd inside ellipse
-Bono and band using the walkway to extend themselves basically halfway out the floor of the arena
-One camera on each band member at *most* times
Built on it tremendously
-Lights in motion around the ellipse instead of stationary
-Light curtains were one of their most original ideas ever, and I say that including the claw stage and ZooTV. Gave them the ability to COMPLETELY change the way the show was both lit and perceived (example: lamps descending for OOTS).
360 in second place solely because it reinvented the modern idea of the PA system, and the screen was admittedly pretty dope.
