Insomniac (Firm)

Beginning in 1997 with a few thousand revelers in Los Angeles, the Electric Daisy Carnival has become the largest dance music event in North America. Known for its displays of pyrotechnics, world-class artists, costumed theatrical performers, interactive art installations, full scale carnival rides and state-of-the-art lighting and sound production, this year's festival in Las Vegas attracted 345,000 attendees from June 21-23, 2013.
