This is the final volume of Kemp English’s pioneering world premiere recording of Leopold Kozeluch’s complete solo keyboard sonatas. It is played, once again, on appropriate authentic instruments and charts just how profoundly Kozeluch’s style changed over the decades, from the charming early Sonata No. 47 for harpsichord to the three late romantic sonatas. The virtuosic Sonata No. 49, with its pedal effects and extended compass, shows techniques derived from the English Piano School and in the final sonata he encapsulates to perfection the sound world of early nineteenth-century Vienna.
