On Friday, February 14, 40 people participated the second annual Hear Below: Listening for Chicago Underground, a free, public event in the programming of the 108th College Art Association Conference in downtown Chicago. This soundwalk navigated through the labyrinthine Chicago Pedway led by Christophe Preissing, Eric Leonardson, and Alex Braidwood.

Read, listen, and learn about the soundwalk’s impact here with observations by Sharon Hoyer and the walk’s co-leaders, plus photos by Katie Wood, and on site audio by Ben Li, mixed by Eric Leonardson.
