2+2=8: Thirty Years of Heidelberg is a retrospective ode to Guyton’s multi-decade outdoor installation, Heidelberg Project. Initiated in 1986 at the site of Guyton’s childhood home, the project was conceptualized as medicine for Detroit’s east side community following the 1967 rebellion. Over the years the project has evolved to span two city blocks, as artistic refuge for locals and visitors from across the globe. Combining painting, sculptural assemblage, and object-based intervention, Heidelberg Project is a cornerstone to Guyton’s robust artistic practice.
