This chapter explores the differences between immersive and reactive audiovisual art. The work of video artists Tony Oursler, Lynn Hershman Leeson, Bill Viola, Pipilotti Rist, and Camille Utterback and musicians John Cage, Brian Eno, and Björk is used to identify the ways in which video, as a medium, can press at the one-way flow of communication that often governs the performance of music and the consumption of visual art. Video technology can give visitors a hands-on, creative role in forging audio artwork, replacing the autonomy of an artist or composer with the spontaneous possibilities of audience-controlled process art. Moving from early interactive video environments to recent pieces that make use of touch-screen interfaces, this chapter charts a progression from communal audiovisual participation to the more interiorized experiences that characterize many contemporary video works.
