Controversy has trailed the rave scene ever since its underground, outlaw origins in the late '80s. In the past decade, promoters such Pasquale Rotella of Insomniac, which is promoting the Electric Daisy Carnival, have turned it into a big business, performing at fairgrounds, racetracks and sports stadiums with corporate sponsors. But since 2006, 14 people have died from overdoses or in drug-related incidents linked to concerts produced by Rotella and another Los Angeles-based rave promoter, Reza Gerami. Last year, Rotella was indicted with five others on embezzlement charges related to events at the Los Angeles Memorial Coliseum. He has pleaded not guilty.
