Idol Structures accompanies an exhibition at the DePaul Art Museum of recent photographs and sculptures by Chicago-based artist Matt Siber, whose work explores the systems of corporate and mass-media communication that permeate the urban landscape. Instead of focusing on the information itself, Siber emphasizes the physical infrastructure of these systems. Photographs of the narrow edges of signs, sculptures of billboard ads hanging so loosely that their text is obscured in the folds, and other unique treatments of promotional materials distort and subvert the intended messages. The artist's deconstruction of such commercial efforts reveals an element of communication meant to remain invisible and subservient to image, text, and graphics. By highlighting the everyday objects used to persuade and influence, Siber's art undermines these communication systems' ability to do precisely what they were intended to do.
