Slide #1

The swarm of festival goers getting in on the Calvin Harris set Sunday night far exceeded the perimeter of the designated tent and I'm pretty sure even the people way in the back and off to the sides were fully jumping during "Feel So Close." But the highlight was Rihanna's surprise (okay, not a total shocker but c'mon it's Rihanna) performance, giving the sweaty crowd 110% and even hopping into the pit with her fans while she belted out songs as Katy Perry decided to crowd surf the sea of hysterical humanity pulsating up against the stage barriers.
