The drunk group of girls standing next to me were talking louder than Grimes' music. I think the sloping parking lot caused some of the pushing to the front. Unless you were really tall or right near the front you couldn't see anything.
last year during best coast, it was so crowded that security wouldn't let bands play until everyone moved to one side of the stage, and nobody wanted to move or give up their spot so we were waiting there forever in the blazing heat and a lot of people just started to leave out of frustration. Also, parking is a bitch.... free festivals always have their downsides!
