Mozart: Sonatas For 2 Pianos, K448 / Sonatas for Piano Duet, K381 & 521 / Adante and Variations, K501 / Martha Argerich, Alexandre Rabinovitch The brilliant Martha Argerich, the pride of Argentina, once again teams with Alexandre Rabinovitch to give us a performance that sparkles with clarity and flawless technique, and will move you with it's passion. If you like your Mozart "soft and pretty", sorry,... this is robust, vigorous stuff. Mozart, who in his youth gave so many duet concerts with his sister, became somewhat of a pioneer in compositions for 4 hands.
