The story of how Mozart fell in love with the young singer Aloysia Weber, was dumped, and then married her younger sister Constanze is well known. The fact that a third sister, Josepha, figured in Mozart's career (and that the youngest sister, Sophia, remembered Mozart from her childhood) is less commonly appreciated. French soprano Sabine Devieilhe steps into the roles of Aloysia, Constanze, and Josepha here, making clear that all three must have been among the strongest sopranos of their time. She doesn't really try to differentiate among the voices of the three (which are at any rate unknowable), but all of them got powerhouse arias.
