James Turrell’s first exhibition in a New York museum since 1980 focuses on the artist’s groundbreaking explorations of perception, light, color, and space, with a special focus on the role of site specificity in his practice. At its core is Aten Reign (2013), a major new project that recasts the Guggenheim rotunda as an enormous volume filled with shifting artificial and natural light. One of the most dramatic transformations of the museum ever conceived, the installation reimagines Frank Lloyd Wright’s iconic architecture—its openness to nature, graceful curves, and magnificent sense of space—as one of Turrell’s Skyspaces, referencing in particular his magnum opus Roden Crater Project (1979– ).
