This book tells the story of the first permanent artwork, Diamonds and Circles, in the UK by the renowned artist Daniel Buren (born 1938), widely considered France's greatest living artist and one of the most significant contributors to the conceptual art movement. Commissioned by Art on the 'Underground', Buren has created a new permanent installation at Tottenham Court Road station in the center of London, famously the location of extensive 1980s mosaics by Eduardo Paolozzi. The artwork, which is set to be completed in late 2016, will become a major feature of the two new entrances and ticket hall of the redesigned station. A conversation between Buren and Tim Marlow walk the reader through the Tottenham Court Road installation and discuss it alongside his other public transport works, while a text by Hans Ulrich Obrist places the work in the context of Buren's wider practice since the 1960s. More than a rare monograph in English on one of the most influential international artists of recent decades, this volume also takes the reader on the fascinating journey from initial artistic concept through to realized physical form in the public realm.
