Watch on HDtoday. Adorno’s Grey features a single-channel video set in the Goethe-Universität in Frankfurt, where German philosopher Theodor W. Adorno famously taught. It shows two conservators scraping the walls of a lecture hall, looking for the legendary grey that Adorno had his classroom painted in order to promote concentration. The excavation is staged as a film set: the technical apparatus of the production is exposed and Steyerl’s directions for the excavators can be heard off camera. The video returns to an image of a camera being set up to take a photo of the lectern.
