I spent my morning at Japan's Modern Divide exhibit at one of my most favorite places in L.A. - the Getty Museum, learning about two Japanese photographers. Hiroshi Hamaya and Kansuke Yamamoto are post WWII contemporary artists that represent the opposite ends of realism/surrealism spectrum. While their frustrations in post-war politics of their country are very similar, the visualization paths they take diverge greatly. I would definitely recommend this exhibition to my L.A. friends, before it leaves town on August 25th.
And while you are at the Getty, you might also want to check out the Looking East: Ruben's Encounter With Asia and Overdrive: L.A. Constructs The Future 1940-1990 exhibits.
