Along the railroad line connecting Chicago with Bloomington-Normal is a marshy wetland at the confluence of the Calumet and Little Calumet Rivers, surrounding the South Deering neighborhood on Chicago's southeast side.

Multimedia artist Norman W. Long started listening in Big Marsh about a decade ago. Calumet in Dub, on view through the weekend at University Galleries, is both a visual and sonic journey, combining photographs, video and music created from field recordings.
