This penultimate volume juxtaposes three early works dating from the 1770s with two mature sonatas from 1809, revealing how far Koželuch’s style changed over a thirty-year period. The early sonatas, though harmonically modest, fizz with Rococo charm and elegance. The late sonatas, meanwhile, were intended for a fortepiano, which had eclipsed the harpsichord, and are two-movement works featuring bustling rondos and deft janissary devices, one of which is the buzzing effect generated by a knee lever on the original 1815 Johann Fritz instrument used in this recording. Kemp English is one of New Zealand’s leading concert performers. Renowned as an exuberant entertainer, he is much in demand as a solo organist, collaborative pianist and specialist fortepiano exponent, relishing the opportunity to work in a diverse array of styles and periods.
