The sixth disc in this highly acclaimed series combine two works in which Mozart's powers as an orchestrator come to the fore. Concerto No. 18 in B flat major, K 456, is sometimes referred to as one of the composers military concertos on the basis of the march-like main theme of the first movement. But more striking is the variety of ways that Mozart employs the various groups of instruments: strings, wind instruments and, of course, the piano. This aspect certainly didn't pass unnoticed by a listener as initiated as Mozart's father Leopold: in a letter to his daughter Nannerl he described how his enjoyment of the orchestral interplay had brought tears to his eyes.
