The 2013 Pitchfork Music Festival, happening Friday, July 19-Sunday, July 21 at Chicago's Union Park, has officially sold out of three-day passes. In its commitment to presenting one of the most exciting, inviting and affordable weekends of music around, in its eighth year, the festival offered the opportunity to purchase more three-day passes than ever before. Those have now all been spoken for, however single-day passes are still available for $50 each. As the summer's most adventurous music festival, featuring an extremely diverse group of established legends, including Belle & Sebastian, R. Kelly, The Breeders, Wire, Swans, Björk, Yo La Tengo, and emerging artists, such as Savages, Disclosure, Autre Ne Veut, Metz, Mikal Cronin, Foxygen, Tree, and Angel Olsen, those single-day passes will be gone quickly! Details surrounding this year's specialty fairs, plus food and drink vendors will be announced in the coming weeks.THE 2013 PITCHFORK MUSIC FESTIVAL LINEUP:FridayBjörkJoanna NewsomWireWoodsMikal CroninAngel OlsenMac DeMarcoDaughn GibsonTrash TalkFrankie RoseSaturdayBelle & SebastianSolangeThe Breeders play Last SplashSavagesSwansRustieLow...And You Will Know Us By the Trail of DeadPhosphorescentAndy StottPissed JeansRyan HemsworthJulia HolterParquet CourtsMerchandiseMetzKen ModeWhite LungSundayR.
