In 2018 Paul Lewis embarked on an exploration of one of the richest bodies of work of the Classical era: the keyboard sonatas of Haydn. For his second volume the British pianist tackles some of the most remarkable pieces in this vast oeuvre including the exceptionally concise Sonata in D major Hob. XVI:51 which is surprisingly pre-Romantic and the celebrated Sonata in E flat major Hob. XVI:52 with which Haydn conferred well-nigh symphonic dimensions on the keyboard sonata for the very first time.
