Using human interaction as his primary material, Rirkrit Tiravanija goes beyond performance to create socially-engaged conceptual works that blur the boundaries of art in novel ways and bridge the division between public and private. Whether by offering visitors free curry in Untitled (Free) (1992) or inviting strangers to drop by and drink tea together in a replica of the artist’s home in Apartment 21 (Tomorrow Can Shut Up and Go Away) (2002), Tiravanija initiates ways to enable the public to be a part of the art-making process, what has been called relational aesthetics. Part social experiment, part ecological program, The Land (1999-) consists of an area of arable land in Thailand that Tiravanija and others transformed into a communally run site for participants to pursue artistic, agricultural, and social collaboration. He won a Hugo Boss Prize in 2004.
