The Emmy Award-winning “L.A. County Holiday Celebration,” a Los Angeles holiday tradition since 1959, joyously returns to The Music Center’s Dorothy Chandler Pavilion to celebrate its 62nd anniversary with a free, live in-person holiday spectacular. The annual event will feature over 20 music ensembles, choirs and dance companies from the many neighborhoods and cultures that make up L.A. Internationally renowned mezzo-soprano Suzanna Guzmán and actor Brian White are back to co-host. Returning performers include the Gay Men's Chorus of Los Angeles, gospel singers Lorenzo Johnson & Praizum, Jung Im Lee Korean Dance Academy, klezmer band Mostly Kosher and two-time GRAMMY award-winning Mariachi Divas de Cindy Shea. Newcomers include Dembrebrah West African Drum and Dance and cellist and autistic savant Adam Mandela Walden. Tickets to the in-person event are free and available on a first come, first seated basis. Doors open at 2:30 p.m., although the line usually begins to form around noon. Proof of vaccination for Covid-19 or a negative test within 72 hours will be required for admission; patrons should allow extra time for check-in prior to getting in line. Masks must be worn throughout the performance. The Music Center’s Dorothy Chandler Pavilion is located at 135 N. Grand Ave., Los Angeles, CA 90012. Parking is free in The Music Center parking garage. Those who can’t make it to The Music Center on Dec. 24 can watch the broadcast on PBS SoCal or stream live online at pbssocal.org/holidaycelebration and kcet.org/holidaycelebration.
