During the shutdown, LACMA has taken to its YouTube channel. Videos include a fun history of NuMU, the Guatemalan museum that found its way to Los Angeles; Vera Lutter on her museum photography; and most delightful of all, a “Brief History of John Baldessari.” The legendary conceptual artist died on January 2, 2020. The film is narrated by his good friend Tom Waits. —E.C.
