Nicholas Bryant, an ordinary investment banker who loves to play the piano, took the stage on a memorable episode of Britain’s Got Talent. His quiet manner and subtle charm revealed little of the spectacular performance that was about to take place. As Nicholas took his seat at the piano, the judges, who were clearly unimpressed, and the audience, who were at best doubtful, settled in.

The atmosphere started to change as the opening chords reverberated across the auditorium. The audience’s initial reservations were rapidly dispelled by Nicholas’s deft, expressive playing. A seemingly simple piano solo quickly developed into something far more elaborate.
