Daniel Buren consistently questions how art is conceived and perceived, and deliberately inverts the relationship that visual artworks maintain with the places where they are exhibited. Because an exhibition site is never neutral, Buren integrates the location's characteristics into the work itself, to prevent the work from being hijacked by its place of presentation. Buren's "in situ" works are deduced from the sites where they take place. They integrate the role of the observer, who by perceiving visually, can understand with minimal exterior information the links between the work and the host location that prompted it. This "in situ" concept enables such works to be eventually replayed like a musical score, and through it, Buren has broadened the artistic field into the entire visual domain. Author Guy Lelong examines the evolution of Daniel Buren's work from the advent of his famous 65-foot striped canvas in 1965 to his large-scale formal apparatuses of recent years. This book illuminates the origins, significance, and inherent revolutionary nature of Buren's art to date.
