Steven Osborne, closing Auckland Museum's 2013 Fazioli Recital series, paired two of the most demanding works in the 19th-century repertoire: Beethoven's Hammerklavier and Schubert's late Sonata in the same key of B flat major.
The Hammerklavier Sonata is a 42-minute titan, with the composer demanding the ultimate in physical stamina, unswervingly logical pursuit and emotional intensity - a triple challenge that posed no problems for the Scottish pianist.
The occasional stray note in the opening Allegro was forgotten within seconds when Osborne set up such an immaculately articulated exposition.
The celebrated Chilean pianist Claudio Arrau felt that its Scherzo's outbursts were signs of aggression; in Osborne's hands, they suggested a wry, well-pointed humour.
While the frenetic outer movements bring a theatrical element to the concert hall, the spacious slow movement allows the pianist to transport his audience on a leisurely voyage of discovery.
