Tomorrowland and Insomniac are collaborating to put on a new EDM festival called UNITY, which will take place at the Sphere in Las Vegas from August 29-31. While the music lineup has not yet been revealed, the 3-day event promises that each night will end with an exclusive closing set from a “world-renowned artist” who will be announced later. While Insomniac is a familiar name in US electronic events, this marks Tomorrowland’s return to America after 10 years, having previously held TomorrowWorld in Atlanta from from 2013 to 2015. “Through the past decades, we both have strived to create festivals and experiences around the world that foster beautiful, unique communities of individuals,” said Tomorrowland and Insomniac in a joint statement. “Now, for the first time in history, our worlds become one. In UNITY, we join together to create a brand-new experience, and there’s no better stage on earth than Sphere.” Pre-sale starts on March 31st, with general public sales beginning on April 7th.
