Pacific Standard Time: Art In L.A. 1945-1980 will bring together more than sixty cultural institutions throughout Southern California to tell the story of the rise of the Los Angeles art scene and how it became a new force in the art world. This unprecedented region-wide collaboration, initiated through $10 million in grants from the Getty Foundation, includes more than 60 cultural partners, 60+ exhibitions, scores of galleries, and an eleven-day performance art festival. While slated to open officially on October 1 and continue through April 2012, we count at least three-dozen exhibitions opening between now and October 1. Here are just a few you should plan to see before this Labor Day.
