DOWNTOWN. MOCA’s primary location is this Arata Isozaki-designed building, but two satellite locations exist at the Geffen Contemporary in Little Tokyo and at the Pacific Design Center. Art offerings range from paintings and works on paper to sculptures and installations. The museum features works by well-known artists like Jackson Pollock, Claes Oldenburg, Mark Rothko, Diane Arbus, Frank Stella, and Piet Mondrian. Emerging artists are also represented.
