Once the Piano Guys were granted a permit to film on the Great Wall, they had to decide on which music to record. As well as including the classical influence, they wanted to include music from Kung Fu Panda, and a musical ‘Kung Fu battle’ section in the middle. They said: “Since The Piano Guys began, it has been our impossible dream to put a grand piano on the Great Wall. People laughed at us when we said we were determined to do it. It is done.” Now they’ve successfully captured the atmosphere of the Great Wall, the Piano Guys’ new dream is to play music on all seven wonders of the world.
