Miami Music Week’s biggest event—the longest-running dance festival in the U.S.—celebrates its 20th anniversary this year. Expect three days of DJ sets, performances and plenty of Instagram-worthy moments and celebrity appearances. Ultra is in for another predictably huge year, as just about every mega-DJ you can name makes an appearance in the phase one lineup: Afrojack, Axwell Λ Ingrosso, Carl Cox, Steve Aoki, Porter Robinson, John Digweed and so many more. The live stage has some surprises too, including the highly problematic but very talented Azealia Banks. And reggae fans are no doubt jumping in their sandals over the addition of the Wailers featuring Julian Marley.
