It was in the SAP Center in San Jose which looked sold out. We are used to smallish tents for Cirque do Soleil performances.
The set design was amazing. It has rear projection so that whole blue thing lights up with video, sometimes different parts have different video running simultaneously. There are doors that open with performers & musicians. The music track was haunting. Skaters come flying down those ramps, even the one that's ten feet off the ground.
Notice the double-ramp right by the arena wall in the lower right of this picture? Skaters fly over that. They must be 8 feet high when they do. The crowd went crazy.
