Christopher was invited by director Jon M. Chu (Crazy Rich Asians) to score a short PSA for Asian Pacific American Heritage Month 2021, to run in AMC Theaters throughout the month of May. They had previously worked together on the Warner Brothers movie 'Crazy Rich Asians', for which Christopher wrote the opening big-band number.
The extended version of the music for the PSA is entitled "Enter the Funk Dragon", and it's a tribute to the history of martial arts in film and TV, starting with Bruce Lee, all the way through the 80s (Karate Kid, 21 Jump Street) and beyond.
The baby in the video is Penny, Christopher's daughter, when she was an 18-month old toddler. (She's a real character.)
