This morning, I realized I'd forgotten to mention something random that happened at Daughtry's show at 1st Mariner Arena Thursday (read the review here).
Before Daughtry's set started, a white sheet was hung around the stage, and squiggles and other shapes were projected onto it (Windows screen saver style). Meanwhile, the speakers played the theme to the original "Batman" movie -- for a few minutes.
It was totally random, and in hindsight, I kinda got a kick out of it. I wonder if other people in the crowd picked up on it.
