Haydn’s piano sonatas, if not as universally familiar in his oeuvre as his symphonies and string quartets, include some of the finest of the time in their genre. On this, his second disc for ONYX, Denis Kozhukhin plays two absorbing works from 1773, the remarkable B minor sonata no.47 from 1776, full of Sturm und Drang, and the E flat sonata from 1789, dedicated to Haydn's close friend Maria Anna von Genzinger, which beautifully combines drama and tenderness.
