I saw this show this past weekend and they used flown JBL equipment inside a 20K seat hockey arena. I will try to post some pics later.
After seeing lots of recent inside concerts with very bad acustics, I made a pledge not to do this again but I don't regret this one. The sound quality was remarkably good - not much sound bouncing off the venue walls.
Anyway, what surprised me was the amount of "canned" music in the performance. I'm pretty certain about 50% of this show was recorded and played back without much assistence from the band on the stage. At one point during one song, the drums, and stage amps and musicians were moved off the stage but the music continued!!!!! I suppose this means Roger does not care about using canned music at a live performance - BOOOOOO!
Maybe I'm wrong but I doubt it. The cartoons flashed on the stage had lots of canned voices and sound effects.
In the two dozen performances I have sen in the last few years, I can't remember much "canned" music, so this was dissappointing.
