Edvard Grieg's Piano Concerto in A minor, Op. 16 (1868) is the most celebrated Norwegian piano concerto, written when the composer was just 24 years old and premiered in Copenhagen. The dramatic opening with its descending cascades and the lyrical second theme have made this concerto a cornerstone of the Romantic repertoire, here arranged for two pianos to capture its orchestral grandeur.
