From the rear cover of this two-volume "Bach's cantatas comprise a vast quantity of superb music written by one of the greatest of all composers. In this standard work, always enlightening and often entertaining, each cantata is discussed as a whole, and the text and musical settings are in almost every case minutely analysed. General questions are also considered, with a penetration derived from a lifetime's experience (Whittaker conducted every one of the cantatas in public). For those who love Bach's music, this is an indispensable guide and source of information."
