Janet Cardiff is best known for her numerous audio works and films that she often creates in collaboration with her partner George Bures Miller. In her ‘walks,’ participants are led through a building or an area of a city by her voice on an audio-guide. With this tool – commonly used in museum pedagogy – Cardiff shifts between past and present, memory and fact, engaging the visitor in the site specific route. Her narrative structure blurs reality with the participant’s own experiences and history. With most of her works Janet Cardiff examines audiovisual perception and the viewer’s illusion. The visitor’s participation is important and every person will have a different experience of the pieces.
