Through his conceptual sculptural practice Johannes Wald strives to explore fundamental questions of working with sculpture. The questioning of the classical sculpture tradition, which defines itself almost always through a strong presence of materiality, has led Wald to understand the actual absence of material as a crucial part of his work. In his new works Wald explores the relationship of material, physicality, and movement. A 2x3m hand-polished steel mirror faces the exhibition space and captures the movements of the visitors. The depiction of movement requires the presence of bodies; in their absence the work is reduced to its sheer material. Behind the mirror, a second work captures footprints in stacked plates of plaster. While the actual body is absent its presence is evoked by its trace.
