The premiere of a documentary about Electric Daisy Carnival at the Grauman’s Chinese Theatre got crowded last night when DJ Kaskade tweeted “ME+BIG SPEAKERS+MUSIC=BLOCK PARTY!!!” and 2,000 people showed up, followed by the LAPD, followed by a “near-riot.”

By 6pm, Kaskade’s tweets turned into “Everybody CHILL OUT!!! The cops are freaking out BE SAFE AND LET’S HAVE SOME FUN!” and by 7:30pm it was “EVERYONE NEEDS TO GO HOME NOW!”

Witnesses say that when the police tried to clear out the crowd, that’s when “the trouble happened.” People got crazy. Cop cars got trampled. Windows got smashed. People “wearing lingerie and elaborate chandelier hats” started trampling police cars and smashing windows.

The madness! The horror! At least Hollywood mascot Paris Hilton got out safely! Wheh…
