Rent Pianomania (2010)

The award-winning film Pianomania follows Stefan Knupfer, Steinway & Sons' Master Tuner in Vienna, as he works with some of the world's best-known concert pianists, including Pierre-Laurent Aimard, Lang Lang and Alfred Brendel. Warm, and at times gently humorous, the film demonstrates how unsung hero Knupfer is pivotal to realising the vision of each virtuoso. A central theme to the film is the year spent by Pierre-Laurent Aimard preparing for the recording of Bach's 'Art of Fugue' and how he works with Stefan Knupfer to identify the right piano and then achieve that elusive perfect tone.
