Composers are often drawn to the musical equivalent of the challenge that faced Jesus feeding the multitude. Most of Bach's Art of Fugue was wrought from a mere 12-note theme and Beethoven famously created 33 variations on one innocuous little waltz by Anton Diabelli.
On Monday evening, Michael Houstoun took up another formidable challenge: playing this Beethoven masterpiece.
Presented by Chamber Music New Zealand as part of the pianist's 60th birthday celebrations, there was nostalgia as well as a preview of Houstoun's 2013 Beethoven cycle, in a short introductory film by Bill McCarthy.
On screen, the pianist remembered his first "solar plexus experience" hearing Rubinstein play Beethoven and was fascinated by stories of the composer's skill at drawing psychological musical portraits - which was the key to the success of the performance to follow.
