Mozart: The Complete Collection just got a little bit bigger. Two new pieces of music have now been identified as compositions of the young Wolfgang Amadeus Mozart, written when he was seven or eight years old. These two pieces of musical history have been in possession of the International Mozarteum Foundation since 1864. Its Research Department Director, Dr. Ulrich Leisinger, who is responsible for identifying these two pieces, joins us from Salzburg, Austria. Also joining us is Terrance McKnight, host of WNYC’s Evening Music.
