David Hockney's bright swimming pools, split-level homes and suburban Californian landscapes are a strange brew of calm and hyperactivity. Shadows appear to have been banished from his acrylic canvases of the 1960s, slick as magazine pages. Flat planes exist side-by-side in a patchwork, muddling our sense of distance. Hockney's unmistakable style incorporates a broad range of sources from Baroque to Cubism and, most recently, computer graphics. An iconoclast obsessed with the Old Masters, this British Pop artist breaks every rule deliberately, delighting in the deconstruction of proportion, linear perspective, and color theory. He shows that orthodoxies are meant to be shattered, and that opposites can coexist, a message of tolerance that transcends art and has profound implications in the political and social realm.
