James Turrell got his start in an abandoned hotel in Ocean Park, creating openings to admit light in precisely controlled ways. Robert Irwin was a near neighbor, conducting similar experiments with scrim, but he has since moved on to undertake a diversity of sculptural projects that include the Getty’s sunken garden and plantings at LACMA. Turrell has remained true to light, treating it as a physical substance and exploring the mysteries of visual perception. Major exhibitions at LACMA, the New York Guggenheim and the Houston Museum of Fine Arts celebrate the genius of this American artist, and provide a unique opportunity to explore the full range of his work.
