Watch Mozart's Sister for free

Maria-Anna Mozart was, like her younger brother, Wolfgang, a child prodigy. Together, the children toured Europe performing as “wunderkinder” to the Kings and Queens of Europe. As a child, there was no issue with performing for an audience, but not so as a woman and she “retired” at age 18, never to play in public again. A startling new discovery has revealed she may be the source of many of the works ascribed to her famous brother. A ‘musical-mystery’ story unfolds around the world with the investigators, their critics, musicologists and historians following why her story has been hidden all this time.
