Filmed over a period of six years.
This is the second piano-related documentary by director Harry Bromley Davenport, the first being his 2013 film American Grand (2013).
Director Harry Bromley Davenport is himself an accomplished pianist, who has composed and performed much of the music for his previous films. He once admitted to an interviewer from Gorezone Magazine that he often prefers to play the piano than work on films.
David Bowie once said of the film's subject, Mike Garson "It is pointless to talk about his ability as a pianist. He is exceptional. However, there are very, very few musicians, let alone pianists, who naturally understand the movement and free thinking necessary to hurl themselves into experimental or traditional areas of music, sometimes, ironically, at the same time. Mike does this with such enthusiasm that it makes my heart glad just to be in the same room as him."
