The problem here are the two large banners flanking the stage. The banners proclaim the city's name in large letters, there were a number of them throughout the event. However, these two are both backwards.
So they put on a show, but it's surprising that no one noticed that these had been erected backwards or flipped around. (It's wasn't particularly windy that I can recall.)
But I suspect that there were a lot of event coordinators wandering around, but this didn't get fixed.
It's minor, but it's a part of your brand.
Have you put someone in charge of the minor details?
