EXHIBITION

Richard Diebenkorn: The Ocean Park Series (Corcoran Gallery, 500 Seventeenth St. NW, Washington, D.C., up through Sept. 23). Seventy-five abstract paintings and works on paper made by Diebenkorn between 1967 and 1987, the years when he was creating the most original works of his career in a studio in the Ocean Park neighborhood of Santa Monica. This brilliantly curated show is one of the most satisfying museum retrospectives ever devoted to an American artist. You must see it, no matter how far you have to travel to get there (TT).
