The first of concert of John Lill’s Beethoven piano sonata cycle at Cadogan Hall saw a warhorse of the concert platform performing one of the great warhorses of the piano repertory. Alongside the concluding Op. 57 sonata – the Appassionata – we heard three lesser-known works, namely Op. 10 no. 3 in D, Op. 22 in B flat, and Op. 54 in F, presented in chronological order.
