Just wanted to add another comment regarding the crowd.
The picture here that I took shows the East side of the stadium.
This side bakes in the sun as the sun sets.
The other side had many more people in the stands. Not full by any means,
but a decent amount of people. The people around me in the pit were very impressed with the band at the conclusion of the set. I overheard a few people 
stating how much that "girl" can rock!
I simply told them, that "girl" is Grace Potter, and this band, just Kicks Ass!!!
