We’re getting ready to head over to Union Park to begin our annual coverage of the Pitchfork Music Festival. Check back later today and all weekend for photos and reviews (including coverage from Jim DeRogatis) of all the music and fashion happening in the temporary village that Pitchfork built. You can find all our coverage here. And be sure to stop by the WBEZ booth to say hi!

To whet your appettite here’s a time-lapse video of an art installation that festival goers are about to get very familiar with. It’s one of two by Chicago’s Johalla Projects. Matthew Hoffman created this one.

The goal of the installations is “to positively shift the mood and environmental aesthetic of the festival and make the experience as much about the effects of ambiance and atmosphere, as the music.” Let us know how they work!
