Up to 115,000 partiers are expected each night this weekend for a dusk-to-dawn sensory salad of electronic dance music, lights, partying and mingling at a sprawling speedway complex outside Las Vegas.

Electric Daisy Carnival officials said Wednesday that all 345,000 available tickets had been sold for the Friday, Saturday and Sunday night event at the Las Vegas Motor Speedway.

The festival founder, Insomniac Events CEO Pasquale Rotella, likes to call the fans and the revelry the headline attraction at his nocturnal gatherings, which drew criticism in Los Angeles before moving to Las Vegas in 2011.

"That's one of the biggest spectacles of the entire event, 115,000 like-minded people all dressed up and having a good time," said Simon Rust Lamb, Insomniac chief operating officer and general counsel. "We want to create moments and memories that are full of joy and that help people create and connect with the people around them."

Hundreds of artists and theatrical performers like fire-twirlers and stilt-walkers are slated to roam the nearly 2-square-mile festival grounds, along with "art cars" blasting music from rolling mock-ups like a pirate ship or a boom box.

Fireworks are planned. Twenty art displays and three graffiti walls are being erected, along with a brightly-lit amusement park featuring several Ferris wheels. Performers include the collaborative fire art group Flaming Lotus Girls and a Rotella creation, Night Owl Experience.

Don't call it a concert. It's a carnival. And don't call it a rave, Lamb said, because that connotes an illegal underground warehouse party.

"The common thread is electronic music," he said. "There's nothing illegal, underground or warehouse about what we do."

The nonstop lineup on seven stages features more than 200 music producers and deejays, including Afrojack, Tiesto, Above & Beyond, Calvin Harris, Madeon, Armin van Buuren, Bloody Beetroots and former Swedish House Mafia member Steve Angelo.

Pat Christenson, whose role as Las Vegas Events president is to attract events to the city and tourists to the hotels, called Las Vegas uniquely able to handle the festival because it has years of experience hosting large events and a remote venue with parking for hundreds of thousands of fans.

"The footprint is big. The music is loud. But it's miles from downtown," Christenson said, "and the way the grandstand is, it's hard to hear the sound outside the speedway."

Insomniac Events has tried to expand the event – and the number of people booking hotel stays – by promoting pool parties, nightclub events and EDMbiz, a $500-per-ticket two-day conference on the business of dance music and culture. It began Wednesday.
