One of the greatest piano players of our time, Leif Ove Andsnes, is asked to host an anniversary concert with the Bergen Philharmonic Orchestra, better known as "Harmonien". It celebrates 250 years as a symphony orchestra, making it one of the oldest in the world. Andsnes, who lives in Bergen, accepts the assignment because Harmonien has had a huge impact on his life and career. The problem for the piano player is that he doesn't know enough about the orchestra's past.
