Their internationally renowned sculpture, video and photographic works look at everyday life and its conceptions of beauty and pleasure, forming an innocent, unpredictable world utterly unique in contemporary art.Peter Fischli and David Weiss' work has been seen at such key international exhibitions as documenta 8 (1987) and X (1997), the Biennales of Sydney (1990, 1998) and Sao Paulo (1989) and the Carnegie International, Pittsburgh (1988), among many others. This is the first true monograph on this extraordinary pair, who will have a major retrospective of their work at the Tate Modern, London (2005-6).
