CHICAGO (CBS) – Sorry, Hall & Oates fans, you won’t see your favorite band headlining Pitchfork Music Festival this year — which isn’t exactly a surprise.

An annual music festival held here in Chicago, Pitchfork Music Festival will take place July 19-21 in Union Park. While most bands haven’t been confirmed — the festival usually has over 40 artists — Pitchfork announced three headliners today: R. Kelly, Björk, and Belle and Sebastian. You can read more about this announcement on WXRT.com.

For those in the know, you’ll note how eclectic a group of musicians this is. R. Kelly, a Chicago native, is regarded as one of the best R&B artists in the world. Björk is known for, well, being bizarre. Dabbling in many types of music, Björk has been successful with many genres, including electronica, jazz, rock and folk. Belle and Sebastian is a popular band that’s never really left their indie roots, playing pop rock, usually with a melancholic twist.

Pitchfork is first and foremost known as one of the leading websites in music criticism. An influence on many, Pitchfork is known to review bands of many genres, though they often concentrate on indie rock. While R. Kelly, Björk, and Belle and Sebastian may seem to have little in common, they definitely represent the wide range of tastes Pitchfork’s many fans — who consist mostly of critical, music-savvy hipsters — have.

By comparison, this year’s headliners seem aesthetically different from 2012’s festival, which featured bands like Feist, Grimes, and Vampire Weekend. Will this deter some from going?

“In my experience the headliner sets are usually too crowded — and I’m too exhausted — to really enjoy,” said Jim O’Brien, who attended 2012’s show. “The stuff earlier in the day is where all the fun is.”

Jim’s statement highlights the fact that many Pitchfork fans stick to their indie roots, going to the festival not for the headliners, but the smaller bands. If that’s how you feel, you might want to wait to buy tickets. If you’ve already been convinced, you can buy tickets here. Individual day tickets will run you $50 and three-day passes are $120.
