Vlatseslav Novikov piano, Anastasia Injushina piano (www.anastasiainjushina.com) Wolfgang Amadeus Mozart (1756--1791) designed his early sonatas for two pianos, four hands for him and his big sister Nannerl to play together and to show off their dazzling Wunderkind virtuosity. The two are captured in a well-known painting showing brother and sister seated at the same keyboard, performing difficult crossed-hand passages under the watchful eye of father Leopold. The challenge is slightly different with two pianos, and the Sonata in D Major for Two Pianos, KV 448, performed with Josepha Auernhammer in November 1781 represents the crowning glory of Mozart's compositions for two pianos in its panache and its irresistible drive.
