Katharina Grosse (b. 1961) is widely known for her in situ paintings, in which explosive color is sprayed directly onto buildings, interiors, and landscapes. She embraces the events and incidents that arise as she works, opening up surfaces and spaces to the countless perceptual possibilities of the medium. In addition to painting on canvas and over found materials like trees, she also creates large polyurethane, Styrofoam, and cast-metal sculptures that act as abstract armatures for her paintings. For Grosse, the process of painting engenders a different kind of temporality than any other medium, as the act of layering colors upon a surface—all painted at distinct moments in time—allows for the multiplicity of possible temporal signatures to be present together on a single plane, undermining the very distinctions between them. Painting across three-dimensional surfaces, as she has done in Untitled (2020), merges this synchronous experience of painting with the protracted reception that occurs when moving around a sculpture.
