This monograph is unusual in bringing the voices from a wide range of people - writers, curators, gallerists, collectors, colleagues, art critics - who have given way to and influenced the artist's work throughout the years. The concept and layout do not only mirror Buren's artistic structures and aesthetics but also his playful way of thinking by offering fragments of works from specific times and letting the reader collect the final pieces herself. The written contributions will be accompanied by a generous amount of visual material.
