The Fire Department shut down the Hard Summer concert at the Forum in Los Angeles over the weekend, declaring the event a "hazard" because people were engaging in "potentially dangerous activities." Hey there fun police, easy now. With performers like DJ Steve Aoki and DJ AM, a little crowd rowdiness should not only be expected, but the sign of a successful show. I mean, if everyone freaks out when the house starts jumping, would there even be a late night scene at the Hamptons?
