Atlanta’s largest EDM camping festival is back for its fourth year, and it’s slated to be bigger than ever. From September 22nd through September 24th, Imagine Music Festival will take over the Atlanta Motor Speedway with its six themed stages. The festival just dropped its first-stage lineup, and its shaping up to be quite a party. In addition to headliners Pretty Lights Live, Above & Beyond, Deadmau5, Tiësto and Gorgon City, the festival will be attracting a bunch of diverse acts from across the electronic-music world. We’re certainly stoked on the Amazonia Stage, which thus far has announced Pretty Lights Live, The Floozies, Ott, Jai Wolf, Rob Garza of Thievery Corporation, Bleep Bloop, Minnesota, among others.Tickets for Imagine Music Festival are available here, and you can check out the first round of artists announced below, with more artists coming in the future.
