Song of the Week: Sergei Rachmaninoff - Piano Concerto No. 2 in C Minor, Op. 18: II. Adagio

Sometimes a piece of music is so familiar you don't listen to it. Sergei Rachmaninoff's second piano concerto is one example, not least because of its appearance in films and other artists' work. But forget all that and listen to a romantic masterpiece. This is the adagio played by Georgian pianist Khatia Buniatishvili.

PS: Sergei is 150 this year.
