This first book in a two-volume set contains documentation of works from 1971 to 1978 by the key Polish-born, Paris-based Minimalist and Conceptualist, Andr Cadere--who died in 1978 at the age of 45. (The second volume, sold separately, is a catalogue raisonn .) Best known for his 1970s Barres de bois rond, wooden bars made of painted cylindrical segments, Cadere regularly upended the status quo by bringing his staff-like sculptural works to openings for other artists that he admired or was close to, such as Robert Ryman or Barnett Newman--whether he was invited to do so or not. The bars inevitably conveyed such strong presence that they intervened with the shows, simultaneously disturbing and initiating discussions on the system of art. This invaluable reference book is divided into historical exhibition views, invitation cards designed by Cadere and photos and stills of his cult-legendary performances.
