I think it's just certain arenas that use it but Quicken Loans uses it for all of its Cavs games, concerts and hockey games.
Went to the Cleveland show and continue to be blown away at how big Brendon keeps getting and how unreal of a performer he is. I had seats on the floor, right in front of the sound stage so when he did his piano thing at the back of the venue, I was about 5 feet away from him. Awesome show, as usual.
