After a vintage period led by Malcolm Bilson and Robert Levin, the 18th-century fortepiano has been neglected in recent recordings of the classical repertoire. But this new series from the 30-year-old South African-born Kristian Bezuidenhout promises great things, and this instalment is superb. The keyboard is perfectly scaled to the music: Bezuidenhout can give the C minor sonata (K457) full force and weight without ever sounding overblown, while the exquisite A minor rondo and B minor adagio have a gentle, unforced eloquence. Both that adagio and the andante of K330 end by shifting minor material into the major mode, to unbearably poignant effect.
