Mozart was a child prodigy who rejected norms and rewrote the rule book. Tonight's concert opens with the overture from The Marriage of Figaro, an opera that changed music and challenged the social status quo.Our performers for this Prom are also out of the ordinary. The international Mahler Chamber Orchestra's members are drawn from 20 countries. They are joined by their multi-Grammy-nominated artistic partner, Norwegian Leif Ove Andsnes, who plays piano and directs the orchestra, as Mozart did, from the keyboard.Together they explore the relationship between soloist and ensemble in the ever-popular, dark and stormy Piano Concerto No 20, and Piano Concerto No 22, in which Mozart pushes orchestral boundaries with the introduction of the then-exotic clarinet.Join Katie Derham and guests for a lively concert of Wolfgang Amadeus.
