Nearly 50 years after his assassination, Martin Luther King Jr.'s regal, melodic voice remains one of our great cultural artifacts — an aural invocation of peaceful resistance and resounding inspiration to global human rights struggles. This MLK Day, celebrate with a multimedia immersion at the California African American Museum. Drop in for family crafts assembled with MLK quotes and collage, or show up for more formal panels and readings with influential artists, academics, politicians and activists. There is a speech marathon for the diehards. Women get their due with a panel exploring how their "pivotal roles," often overlooked, helped shape the movement. While you're there: CAAM's 4,000-piece-strong permanent collection is shaped by a mission to "think expansively" about the cultural contributions of African-American artists — and the rose garden is a few steps away.
