After hearing acclaimed pianist Lang Lang play, you'll see why he was named one of the world's "most influential" people by Time magazine in 2009. Here, at Vienna's Musikverein concert hall, Lang records performances of Beethoven sonatas for the first time, including No. 3 in C Major, Op.2 and No. 23 in F Minor, Op. 57, as well as works by Prokofiev, Chopin, and Albéniz.
