Well, here's something you don't see everyday, even in a festival-laden city like Chicago: A music festival set inside a giant maze. Yep, Empty Bottle Presents and Trouble construct a labyrinth in Pilsen's Thalia Hall structure (dubbed the 1807 S Allport Maze) for the month-long event. As you might expect, it's part experiential art project, part avant-garde concert. Filling the corridors are a bevy of ambient, noise, art-rock and electronic experimenters, including Zs, Tim Kinsella, ONO, John Elliot of Emeralds and more. Check out the Bottle site for details.
