Well it looks like Las Vegas will be the new home to Insomniac Events' Nocturnal Wonderland 2014 and Beyond Wonderland 2015 (said to return to SoCal in 2015 as well).
“Three years ago we had no outdoor music festivals in Las Vegas and now by 2015 we will sell a million tickets at festivals along the Strip,” said Pat Christenson. “They are putting together music with food and art and creating events that are bigger than just a concert.”
So just where is this location? The property is located behind the Linq and is owned by Caesars Entertainment.
