Mozart wrote a series of masterpieces and revolutionized the nature of the piano concerto. The five piano concertos, Nos. 20-24, are game-changers in the history of the form. Mozart began to re-examine the roles of the soloist and orchestra and created a dialogue between the two entities in a way that had not been heard before. “It changes completely with Mozart’s Piano Concerto No 20 [in D minor K466],” says Andsnes. “This is the moment, which points to the future and the development of the piano concerto and of the beginning of the Romantic piano concerto, which is so beloved.”
