The crowd gathered at Grauman’s Chinese Theatre for the premiere of a documentary about the Electric Daisy Carnival, a rave that is now banned at the Los Angeles Memorial Coliseum after a 15-year-old girl died from a drug overdose last summer. A party hosted by DJ Kaskade was scheduled to follow the film, Rayner said.
