I didn't even know that Owl City was opening, but I LOVE them, so I was pleasantly surprised. A has even created a "Fireflies" ringtone for me.
So, don't hate me, but I've never loved John Mayer. There have always been songs I've liked, but I have been known to hit the skip button on Pandora on occasion. Well, this concert has totally changed my opinion. I have a whole new appreciation for Mr. Mayer. It was a great concert.
Because I was there early for set up, I got to see John rehearse! That is him, on stage, behind me.
