LAS VEGAS (AP) -- Organizers expect more than 140,000 people to descend upon the Las Vegas Motor Speedway each night for the Electric Daisy Carnival.
The three-night rave that kicks off Friday features the biggest names in electronic dance music, plus carnival rides, fireworks and other spectacles.
A study commissioned by parent company Insomniac estimates that last summer's event injected $278 million into the Southern Nevada economy. Attendees paid for about 92,000 hotel room nights and spent more than $45 million on food and beverage.
The study says nearly 95 percent of attendees traveled from outside the Las Vegas area to attend.
It's EDC's fourth year in Las Vegas. The event moved from the Los Angeles Memorial Coliseum amid controversy over the 2010 death of a 15-year-old attendee who was treated for drug intoxication.
