Once again that rare bird has arrived—the work-free Monday. To celebrate Martin Luther King Day, LACMA is free all day. This is your last chance to see A Tale of Two Persian Carpets: The Ardabil and Coronation Carpets, which closes after today. And a couple of other shows—From the Spoon to the City and Heroes and Villains—are nearing the end of their runs as well, making today the day to come check them out before they’re gone forever. We’ve also got live music and dance performances in the afternoon, just for a little extra incentive.
