This essay is a reflection on the site-specific performance You are Here, created by Charles Campbell and Steve Epley on the roof of the University of Minnesota Tate Lab of Physics in May 2002. Scott Magelssen treats the production within the context of the previous site-specific work of Campbell and Epley, and their Minneapolis-based theatre company Skewed Visions, exploring the project's themes of knowledge-production and memory, the company's unique use of space, and the actor-object mode of performance. Scott Magelssen is Assistant Professor of Theatre Arts at Augustana College, Rock Island, Illinois, where he teaches theatre history and dramaturgy, advises the student-run experimental theatre group, and occasionally directs productions. His current research focuses on the performative and historiographic practices employed by outdoor ‘living history’ museums in Europe and the US.
