Carl Philipp Emanuel Bach was more famous in his lifetime than was his father, and his reputation largely rests on his keyboard music. There are more than 60 keyboard concertos, and even more sonatas and short pieces of various types. Miklos Spanyi is involved in an ongoing survey of the complete concertos, so it is only logical that he should also take on the solo works as well. C.P.E. Bach's music is impulsive, surprising, and frequently very emotional, with extensive use of minor keys. The Prussian Sonatas are early works, dating from the 1740s, which accounts for the clavichord as instrument of choice. Spanyi is a powerful advocate of the music, playing with exemplary taste and virtuosity.
