The summer is not over yet? If that is so, let’s celebrate one more sunny day with one of the most beautiful double-concertos I know of. Sparks of joy, energy and vitality mark this piece, which had to be considered avant-garde at the time of its composition. In the year 1740, the Baroque era was drawing to its end and composers in the wake of Johann Sebastian Bach were bridging the gap to the Vienna classics era. One of these composers was Carl Philipp Emmanuel Bach, the second son of Johann Sebastian Bach. Just like the keyboard concerto I have presented in an earlier post in July, today’s piece foreshadows the modern concertos that Wolfgang Amadeus Mozart and Ludwig van Beethoven would write several decades later.
