Rubinstein - Chopin Polonaise in A Flat Major, Op.53 (Live!)

Arthur Rubinstein plays the great Polonaise in A Flat Major, Op.53 by Frederic Chopin. Performed live! After hearing this performance, I now know exactly why Robert Schumann said of Chopin's music that one can find "guns buried in flowers".

Performed in Febuary 1960, Warsaw. (Thanks to huismanq for this information)
