“The idea becomes a machine,” said Sol LeWitt, “that makes the art.” Born in 1928, in Hartford, Connecticut, LeWitt went on to study at New York’s School of Visual Arts. Once out of school, he painted during the day and worked as the night receptionist at the Museum of Modern Art. There he became friends with other aspiring artists who were working at MoMA—Dan Flavin, Robert Ryman, and Robert Mangold—and they encouraged his cerebral approach to art making. By the mid–60s, LeWitt’s geometric constructions broke new ground. His belief that it was the planning and intellectual process that comprised art (execution was a perfunctory detail) made him a pioneer of Conceptual art and Minimalism. In Sydney, this imaginative exhibition places LeWitt’s work in conversation with Anmatyerr artists Emily Kame Kngwarreye and Gloria Tamerre Petyarre. —Elena Clavarino
