Carl Philipp Emanuel Bach is the perfect embodiment of the rebellious son. His keyboard sonatas sparkle with the brilliant counterpoint learned from his father Johann Sebastian but are punctuated with passages that are decidedly his own; sudden changes of mood take flight with whimsical melodies that throw us into the Classical era. This is particularly apparent in the opening movement of the F sharp minor sonata, thrillingly played by Danny Driver, whose vivid handling of the later C minor and A major examples illustrates just how far CPE had moved away from his father. As if to underline the point, Driver adds the thoroughly Mozartian Fantasie in F sharp minor and Rondo in D minor. Immensely rewarding listening.
