The standard piano keyboard stands about 72 cm (28.5 inches) above the floor. A few biometric approximations leads me to believe that the pianist performing Libertango in today's featured video stands 4.37 meters (14 feet, three inches) above the floor.
The pianist goes by the name of Uno and although "Giant" may not be the appropriate description, he is certainly tall enough to take the world's record away from Bao Xishun.
