It's with particular pride that Angelenos who have known of Lari Pittman both as a painter of consummate skill and intelligence as well as a professor at UCLA who has launched so many other careers can now point to the Hammer Museum's coming retrospective of his work. Pittman's work was social media clickbait long before social media even existed and in this and many other ways he presaged so many different strands of the current artistic climate. MoCA's coming Pattern and Decoration show will complement this one, so it's a good time to visit.
