Events: Christmas Eve musical fest at the Dorothy Chandler Pavilion

For six hours on Christmas Eve, more than 40 musical groups representing the diversity of Los Angeles will host a free (even parking!) alfresco performance at the Music Center downtown. That should warm the cold, tuneless heart of any Grinch. Dorothy Chandler Pavilion, 135 N. Grand Ave., L.A. 3-6 p.m. Fri. Free. lacountyarts.org.
