In a lecture performance, artist Dan Graham discusses three of his crucial time-delay works: Present Continuous Past(s), a stage set for a Glenn Branca musical performance at the Kunsthalle Bern, and an unrealized project for local public access cable TV. Furthermore, Graham also shows three examples of low-tech-pioneer video art by Darcy Lange, Nam June Paik and Bruce Nauman to counter the current fashion of video art as spectacle.

Dan Graham is an american artist who is showing extensively in America and Europe. Notable exhibitions include documenta 5 (1972) and the Venice Biennale (1976). In 2009 a large retrospective of his work was on view at the Museum of Contemporary Art, Los Angeles, the Whitney Museum of American Art, New York, and the Walker Art Center, Minneapolis.
