After a career spanning decades, Gustav Metzger is now in greater demand than ever, generating new projects as for Münster Sculpture Projects 2007 or realising earlier ideas, as with Project Stockholm, originally conceived in 1972 for the UN Environmental Conference in Stockholm. Now produced for the Sharjah Biennale (2007), the huge installation consists of 120 cars that discharge their exhaust fumes into a plastic structure. For Talking Art, Gustav Metzger is interviewed by Andrew Wilson, Curator of Modern and Contemporary British Art at Tate.
