While Santa may still be working with his elves to load up his sleigh, you can relax and enjoy a pre-Christmas Eve celebration at the Dorothy Chandler Pavilion. Gather up your friends and family and go hear L.A.'s biggest holiday show, which includes more than 20 choirs, music ensembles and dance troupes from all over the city. The free three-hour show celebrates LA's multicultural observation of the holidays with everything from an all-female mariachi ensemble to a Korean dance troupe. Doors open at 2:30pm and guests are encouraged to come and go as they please throughout the show. Reservations and tickets are not necessary; parking at the Dorothy Chandler is also free. Those who still have last-minute holiday responsibilities to attend to can listen to a live stream of the concert on PBS SoCal.
