Sylvia Milo tells the story of Wolfgang Amadeus Mozart’s equally talented (and internationally ignored) older sister.

Most people are familiar with the story of Wolfgang Amadeus Mozart, the 18th-century Austrian child prodigy who played before the crowned heads of Europe and went on to compose an astounding canon of work in his relatively short life-span, much of which is still popular today. Far fewer know that in his earliest tours, he took second billing to his older sister, Marianne, who was a virtuoso in her own right. Writer and performer Sylvia Milo illuminates that relatively unknown story with her fascinating and irresistibly intelligent one-woman show, The Other Mozart, now making its New York premiere at HERE Arts Center. Marianne, or Nannerl as her family knew her, was eight when she began taking harpsichord lessons from her Joe Jackson-like father, Leopold. Her three-year-old brother, Wolfgang, joined in the lessons, even though Leopold never allowed Nannerl to play at such a young age. Soon, the two wunderkinder were touring Europe as a double act. Yet once Nannerl was of marrying age, she was kept at home, while Wolfgang continued to perform. She eventually married a lesser nobleman and went on to live a long life in relative obscurity. Meanwhile, her brother flamed out spectacularly, but went on to be known as one of the greatest composers who ever lived.
