An impromptu street rave announced on Twitter to celebrate the Hollywood screening of a documentary about the [article id="1642541"]Electric Daisy Carnival[/article] nearly turned into a riot on Wednesday night when police attempted to disperse a huge crowd that gathered on a downtown street.

Popular electronic musician Kaskade tweeted about a special DJ set earlier in the day, telling fans to gather at 6 p.m. in front of Grauman's Chinese Theatre, promising, "Me+BIG SPEAKERS+MUSIC=BLOCK PARTY!!! RT!"

The show was intended to celebrate the debut of the rave documentary "Electric Daisy Carnival Experience." But when hundreds of dancers converged on the invitation-only premiere and began throwing bottles and other objects at police, who were trying to disperse them, officers in riot gear responded in force, according to the Los Angeles Times.

While invited guests tried to get into the screening, thousands of non-ticketed dance fans converged en masse and ran up against police, who were trying to clear Hollywood Boulevard for the premiere. According to The Hollywood Reporter, the near-riot happened when the street dancers ignored warnings from cops that Kaskade's set had been canceled and that they should disperse. Even after Kaskade sent out some follow-up tweets telling fans to "chill" and leave the area, officers were forced to push crowds away from the Grauman's entrance, setting off the clashes.

The movie, directed by video legend Kevin Kerslake, chronicles the 2010 edition of the massive music festival, with interviews from such stars as Kaskade, David Guetta and Steve Aoki.
