Even Mozart’s great series of piano concertos did not exist in a vacuum.

The Czech composer Leopold Kozeluch was a contemporary of Mozart, living and working in Vienna during the 1780s. The two knew each other and Kozeluch similarly sought to make his living as a pianist-composer, author of 22 keyboard concertos.

Howard Shelley and the London Mozart Players make a persuasive case for his Piano Concertos Nos 1, 5 and 6, where classical refinement and ebullience go hand in hand.

This may be Mozart with the genius switch turned off. Worth investigating, nevertheless.
