An impromptu music block party thrown by DJ Kaskade outside the premiere of a movie about the Electric Daisy Carnival turned into a mob scene Wednesday night, when the crowd refused to disperse.
Kaskade announced the event Wednesday afternoon via Twitter: "Today@6pm in Hollywood @Mann's Chinese Theatre. ME+BIG SPEAKERS+MUSIC=BLOCK PARTY!!! RT!"

The premiere had been promoted for weeks, with an after-party to follow at Supperclub, featuring a performance by Kaskade.
Police say the event was by invitation only, but many people showed up without invites, and were turned away by security.
The LAPD shut down Hollywood Boulevard between Highland and Orange avenues after hundreds of people gathered.
Police ordered the crowd to disperse, but many refused to leave, and began fighting and throwing bottles.
Some people jumped on police cars, smashing windows.
Officers in riot gear used bean bag guns to subdue the crowd, and several arrests were made.
The Hollywood/Highland Red Line station was closed, and Hollywood Boulevard buses were being detoured due to the disturbance.
Kaskade took to Twitter amid the chaos, saying that the party was over and urging people to calm down.
"EVERYONE CHILL NOW!!! The block party has officially been shut down! BUT THIS IS TOO CRAZY AND WE NEED TO BE SAFE!," Kaskade tweeted.
"I AM REALLY CONCERNED FOR EVERYONES SAFETY AT THIS POINT! PLEASE RELAX," he also said.
Finally, he pleaded, "EVERYONE NEEDS TO GO HOME NOW! I DON'T WANT THIS TO REFLECT BADLY ON EDM OR WHAT WE ARE ABOUT. BE RESPECTFUL AND CHILL OUT!!!
Supperclub also posted on its Twitter page, asking people to stay away if they did not have tickets.
"For the safety of our community, DO NOT COME TO SUPPERCLUB tonight. We are grateful for everyone for helping to make this an AWESOME night!"
Insomniac Inc., the organizers of the movie screening, issued a statement saying they were "disappointed that a small group of people would try to mar a private documentary screening."
Authorities say Kaskade did not have a permit for the concert.
The Electric Daisy Carnival Experience is a film about the music festival by the same name, which is attended by tens of thousands of people.
It made headlines when a 15-year-old girl died of a drug overdose at the event held in July 2010 at the Los Angeles Memorial Coliseum.
The event was subsequently moved from Los Angeles to Las Vegas.
