i went both years. i liked last years cuz it was at an outdoor ampetheatre so the slanted lawn was a lot better to sit on than a parking lot. BUT the actual location of this years was amazing, being on the water having the skyline/bridge/stadium behind you, much better screens, and good quality sound. another thing i liked about last years was that it was all on one stage so you didn't miss anyone, where this one had the main and indie stage. it was hard to choose who to go see, and whether or not you wanted to give up your spot/make it through the crowd.
overall i'd say that this concert series is just becoming better and better as each year progresses. so we definately have something to look forward to next year.
