For over 50 years, British artist Phyllida Barlow (born 1944) has created astonishing sculptures and expansive installations. Using simple materials such as plywood, cardboard, fabric, plaster, paint and plastic, Barlow's physically impressive and materially insistent sculptures ask questions about our relationship to objects, and about objects' relationships to us. Slipping between different registers of form and meaning as we try to understand them, her sculptures are like things caught in the process of becoming other things, things we might have seen before or may see in the future. Reproducing many works never seen before, this major monograph presents more than 100 works, offering an indispensable resource on the practice of this important British sculptor, who continues to be lauded by artists and critics for her work, and who has influenced several generations of artists.
