The billed acts continue to impress; an Outkast reunion, Jack Johnson (whose sound is perfect for the beach), Fitz and the Tantrums, Bastille, Pretty Lights, The Avett Brothers, Tegan and Sara, Queens of the Stone Age, Capital Cities, The Black Keys, Amos Lee, Zedd, Childish Gambino, and more totaling over 60 performances. Although the Hangout ??officially?? starts on Friday, organizers have put together a pre-festival kickoff party that has included performances by Girl Talk, Iron & Wine, Wolfmother and Dumpstaphunk. There are also pre-shows at various bars throughout the city for months leading up to the festival weekend.
