Deerhunter Playing 'Secret Generator' Show At Undisclosed Chicago Location

Atlanta-based indie rock group Deerhunter is coming for a free concert in Chicago this Saturday.

Where exactly that concert will be held is up to you to figure out.

Urban Outfitters and Levi's are teaming up to sponsor the "Secret Generator Series," a string of concerts in selected cities whose locations will stay undisclosed until just before the start time.

Instead, the Secret Generator Series blog is posting photos, one at a time, of the venue, and encouraging savvy readers to try to figure it out.

The catch is this: the concerts are powered only by a portable generator (hence the name), so they could be held anywhere in the city. Don't expect the answer to be Millennium Park.

So far, the blog has released two photo clues for where the Deerhunter concert this weekend will take place. From the looks of things, it's near some segment of the river, and by a highway overpass.

Can any sharp-eyed readers out there spot the venue?
