Borrowing from the title of Andy Warhol’s 1965 double-screen film, Outer and Inner Space, this book explores how video art addresses the interplay between external reality and internal states of mind. Three recent video installations -- by Pipilotti Rist, Shirin Seshat, and Jane and Louise Wilson -- are placed in the context of forty influential early works from the late 1960s to mid-1980s. These pairings underscore both the change and the continuity in video art, from its rough-edged experimental origins to works that use sophisticated technology to create environments of image and sound.
