Mozart's genius was the font of a sea of buoyant melodies, arrestingly beautiful orchestrations, and virtuosic solo performances. His best works are here, providing hours of passion for new and old fans alike: The delicate, glistening Concerto No. 20 in D Minor for Piano and Orchestra is a stunning exhibition of harmonious cooperation; Symphony No. 40 in G Minor is a rumbling collection of some of the composer’s finest lyricism; and the fateful, incomplete Requiem contains transcendental moments of calm and turmoil.
