New York-based artist Tauba Auerbach works in series, pushing one subject to the point of conceptual exhaustion before moving to the next. Her early works (currently on view in “Ecstatic Alphabets/Heaps of Language” exhibition at MoMA), take apart familiar systems of signification — the alphabet, punctuation, Morse code — and reassemble their elements so as to de-familiarize them. “Fold” paintings are created through a process of creasing canvas, spray-painting its contours, and stretching the result. In the “Weave” series monochromatic strips of white canvas are threaded across a wooden frame, producing an orderly weave disrupted by rays, slices and waves of divergent patterns. Collapsing the boundary between two and three dimensions, Auerbach’s “Fold” and “Weave” series trouble Cartesian spatial logic, proposing a fluid and manifold alternative.
