Let's be honest. In the tradition of live shows, crowdsurfing has to be one of the greatest. AWOLNATION weren't messing around when, at this year's ACL Music Festival, frontman Aaron Bruno took to the crowd with an actual surfboard...and actually showed some impressive skill! From there, the band jumped full force into the smash hit "Sail," spurring some continued crowd surfing from audience members. Still not sure which was more impressive: the surfing or the performance. We'll leave that for you to decide...
