Volume number 10 in the Conversation Series with the influential museum director, curator, writer and conversationalist Hans Ulrich Obrist, is given over to an intensive talk with the important German conceptual artist, Thomas Demand, who constructs precise environments out of paper maquettes, which are then photographed to haunting effect. Topics include concepts and rules of operation, the reconstruction and reverberation of history, work processes, studio realities and significant exhibitions of recent years. This wide-ranging conversation, modestly illustrated with black-and-white images, is as intelligent as it is revealing, giving the reader an unprecedented glimpse into the minds of two of the most brilliant players on the international art scene. Demand lives between Berlin and New York, where a retrospective of his work was shown at The Museum of Modern Art in 2005. Hans Ulrich Obrist is the Co-Director of the Musee d"Art Moderne de la Ville de Paris, as well as the Serpentine Gallery, London, where he lives and works.
