Pitchfork Music Festival 2013 is the indie alternative to major festivals like Bonnaroo, Coachella and Lollapalooza that features plenty of great acts but on a smaller scale. The Internet music publication just announced that R. Kelly, Björk and Belle & Sebastian will be the headliners as well as ticket information.

Pitchfork prides itself on diversity, and, if the headliners are any indication, the 2013 iteration of the festival will be its most diverse yet. Pitchfork Music Festival will once again take place at Union Park in Chicago, Ill., July 19-21.

Initially, the Pitchfork Music Festival stuck close to its indie aesthetics with acts such as the National, Yo La Tengo, the Walkmen, Grizzly Bear, Bon Iver, Vampire Weekend, Beach House, Dirty Projectors, M83 and the Antlers, but the festival has continued to expand and diversify its lineup. Previous lineups have included a “Don’t Look Back” night where Sonic Youth, Slint and GZA performed one of their classic albums in their entirety.

Last year’s lineup was even bigger and featured not only the best upcoming indie acts but plenty of emerging hip-hop artists. Kendrick Lamar, A$AP Rocky, Wills Earl Beal, AraabMuzik and Danny Brown played alongside Feist, Beach House, Vampire Weekend, Godspeed You! Black Emperor, Grimes, Chromatics, Ty Segall, Wild Flag, Real Estate and Youth Lagoon at Pitchfork Music Festival 2012, and the festival sold out well advance of the festival.

R. Kelly has been a R&B pioneer and Grammy winner with several No. 1 hits including “I Believe I Can Fly,” “Bump n’ Grind” and “Ignition (Remix).” as well as the “Trapped in the Closet” project. Björk continues to defy any classifications and is an interesting and ever-evolving musical talent, while Belle & Sebastian have just recently reunited and were one of the best 1990s indie rock bands.

Tickets are now on sale, and three-day passes cost $120, while single-day passes are also available at $50. Expect Pitchfork to announce the lineup of artists, as well as other activities, such as craft food vendors and curated art installations.
