In the past decade John Lill has become so identified with Beethoven - the piano concertos and the sonatas - that it came as a pleasant surprise to find him marking his 60th birthday with a programme ranging across a much wider repertoire. There was some Beethoven to begin, but that was followed by Brahms, Chopin and Prokofiev in a recital that provided a timely reminder of Lill's wide-ranging strengths as a soloist.

Lill is a pianist entirely lacking in unnecessary frills. What you see on the platform - a brisk, business manner, with not a trace of an attention-seeking gesture - is what you get in his performances. His music-making is totally purposeful and to the point, and has no truck with anything superficial.

Such severity works best in mixed recitals like this; what can seem a bit dull in an undiluted programme of Beethoven seemed admirably controlled and clear-eyed when just the Moonlight Sonata was involved. Brahms's Variations and Fugue on a Theme of Handel had a similar rigour, for Lill never goes out of his way to cultivate a beautiful tone and, apart from a brief slackening of tension around the midpoint, the trajectory of the work towards the culminating fugue was majestically followed.

The Chopin provided the surprise of the evening. One might have expected such an unflashy pianist not to respond instinctively to such lyrically expressive music. But Lill's intelligent account of the Polonaise-Fantasie Op 61 recognised it for exactly what it is: an astonishingly original piece of musical architecture in which every detail counts. After that his tireless fingers negotiated Prokofiev's Eighth Sonata impressively, taking him smoothly through the arch of the first movement and the bittersweet mannerisms of the minuet, before the torrential final toccata.
