The story of the other Mozart, Maria-Anna, a child prodigy forgotten to time, as seen through the eyes of musicians, musicologists, and researchers. 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. 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.
