A massive shuffle is under way among some of the world’s biggest electronic DJs, Las Vegas sources say. We hear a number of big-name DJs including Calvin Harris and Deadmau5 — who have exclusive deals with casino mogul Steve Wynn — may be leaving the Wynn Group to go to other clubs. Sources estimate Wynn doled out $25 million to snag top names, including Harris and Deadmau5 along with DJ Tiesto, David Guetta and Afrojack to perform at his nightclub venues this year and to lock them in for big events like New Year’s Eve. But those contracts restrict spinners from performing in other venues, and sources tell us the DJs have grown frustrated. “They are trying to get out of their contracts because they don’t want the restrictions,” said one club insider. We also hear that other venues “are trying to make plays for these artists, and they might be successful in getting them.” Sources told us execs at Angel Management Group, which is developing the 75,000-square-foot Hakkasan restaurant opening in the MGM Grand later this year, have offered big money to Harris and Deadmau5 to perform there. A rep for the Wynn told us: “We have established wonderful partnerships and lasting relationships with members of our exclusive DJ roster, and we look forward to announcing our 2013 lineup soon.” Neil Moffitt, Angel Management Group’s Chief Executive Officer told us: “We’re looking forward to a great opening of Hakkasan Las Vegas in the spring of 2013 and expect to have some of the biggest names in the DJ business to help us celebrate the launch.”
