36. Union Park (Pitchfork)
Address: 1501 West Randolph St.
Pitchfork, the most hotly-debated music website out, launched their festival in 2006 at Chicago's Union Park. In the ensuing years, the festival has become a serious competitor to the other major festivals in terms of booking ability. What sets Pitchfork apart from Coachella and Bonnaroo is the clear editorial eye at work. If a band or artist isn't well reviewed by the website, that band or artist won't be booked. In recent years, the website has become more and more enamored with the best in hip-hop; for the upcoming 2012 festival, performers include Kendrick Lamar, A$AP Rocky, Clams Casino, and Big K.R.I.T.
