For the first 16 years of her life, Mozart’s sister shared equal billing with her brother. Musical partners and collaborators, Wolfgang Mozart and Maria-Anna Mozart played together before Kings and Queens, and were the talk of Europe. What happened to her? Forced to withdraw from public life because she was a woman, a stunning new investigation explores why she was retired and what happened to her music. From multi-awarded Director/Producer Madeleine Hetherton-Miau and Producer Rebecca Barry, Mozart's Sister is a ‘musical-true-crime’ story that explores the lost talent of Maria-Anna Mozart.
