The keyboard sonatas of C.P.E. Bach (1714-1788) bear hallmarks of a composer who lived through a significant moment in musical history: he composed his works during the transition from the Baroque to the Classical period. These works are musical landmarks that epitomize the style and values of an era. The Preussische and Werttembergische Sonatas, collected together on this new 3-disc set, exemplify Bach's celebrated style of composition, and reveal the impact of the period's stylistic influences.
