Looking at the recent works of Sebastian Stumpf one finds an interplay between performance and the recording of performance, between the execution of a physical act and the documentation of it by means of a camera. [He] operates in two distinct realms: in the empty spaces of contemporary art institutions and in urban settings with their preexisting orders. […] An inconspicuous architectural detail suddenly becomes the catalyst for a physical exploit…. The art gallery becomes a space for action. Or by an act of functional mobilization the city and its walls, columns, trees, garages, bridges and passage ways become a kind of practice field.
