This year's Pitchfork Music Festival in Chicago, Illinois is starting to round off its prized billing.

Added to the three headlining acts of R. Kelly, Bjork, and Belle & Sebastian, which were announced in early February are a strong crop of mid-tier acts. Included in the recent additions are; Joanna Newsom, The Breeders (performing all of the band's seminal LP Last Splash), SwansEl-P, Killer Mike, TNGHT, Chairlift, and many others.

More acts will be added to the lineup leading up to the July 19-21 event, which is in its eighth official year.
