A group of world-renowned performers join President Barack Obama in the 86th National Christmas Tree Lighting Ceremony. The group of performers includes Steinway Artist Brad Mehldau. All of the event’s performers who played piano or had piano accompaniment used a Steinway Model D concert grand piano (CD-381) from Steinway & Sons bank of concert pianos. This piano has been delivered from Steinway Piano Gallery in Washington, DC for the event, and technicians had spent over 9 hours preparing the piano, to be in perfect playing condition for the performances.
