Avicii, M.I.A., Guetta to headline Ultra Music Festival

For Phase One of 2014's lineup, Ultra Music Festival has announced 21 headliners for the three-day party in Miami (March 28-30), according to Billboard. David Guetta, Tiesto, Avicii, Diplo and M.I.A. are on that list as well as Armin Van Buuren and Kaskade. In its 16th year, Ultra has been the unofficial kickoff of EDM festival season, along with Miami Music Winter Conference. Last year, Swedish House Mafia bid farewell to the turntables while Avicii premiered his country/folk crossover hit, Wake Me Up! A score of live acts will also be on hand including M.I.A., who will be making her Ultra debut, as well as Dizzee Rascal, MGMT and Basement Jaxx.
