But now they've just gone cray cray.
The festival announced headliners this morning via Twitter for its 2013 edition: Belle & Sebastian, Bjork and -- @#$%! -- R. Kelly.
You've read that correctly. And I have confirmed, just in case, that the Twitter account was not hacked.
Pitchfork president Chris Kaskie told the Sun-Times this morning: "R. Kelly, like Bjork and Belle & Sebastian, continue our goal of presenting both the most exciting emerging music today all while celebrating some of our favorite artists ever. We couldn't be more excited about these headliners, and frankly cannot wait to get the rest of the lineup out there!"
Kelly remains notorious not only for his 20-year solo career, drenched in overtly sexual R&B, but for his 2008 Chicago trial on child pornography charges, for which he was acquitted. His last two albums, "Love Letter" and "Write Me Back," have been more traditional, respectable affairs, though Kelly revived his bizzaro musical soap opera "Trapped in the Closet" in November and has promised that his artistic goals now are back to "shocking people."
The festival teased yesterday on Twitter that it would be announcing headliners today. The full lineup of the usual dozens of acts will be announced in the weeks ahead.
Pitchfork 2013 throws down July 19-21 in Union Park.
Three-day passes ($120) and daily tickets ($50) to the festival are available now.
