CPE Bach's flute sonatas are among the highest quality and most beautiful contributions to the genre.

The circumstances of their composition are unknown, but it is likely that at least some of these works were inspired by one or more flutists from Bach's circle in Potsdam and Berlin. However, Bach's employer Frederick the Great is almost inevitably ruled out as an addressee because of his conservative musical tastes.

Performed on period instruments, Karel Valter (transverse flute) and Hadrien Jourdain (Silbermann fortepiano) are able to win new friends for the music of Bach's most innovative son.
