Pitchfork Music Fest returns to Chicago’s Union Park this weekend for an eighth year. And this year, controversial R & B star R. Kelly is one of the headliners.

Kelly was accused and then acquitted of making child pornography, but allegations about relationships with underaged girls have dogged him for years.

WBEZ’s music blogger and Sound Opinions host Jim DeRogatis wanted to know: Can you separate the art from the artist? Jim talked to a series of colleagues in the music world to get some answers and opinions, and shared that material with the Morning Shift’s fill-in host Randi Belisomo earlier this week.
