Soprano Anna Prohaska and violinist Patricia Kopatchinskaja are both well known for their taste for eclecticism, experimentation and adventure. As they are also are friends, it was only to be expected that one day they would devise and record a programme together, and here it is: Maria Mater Meretrix... What is the relationship between Hildegard von Bingen and Gustav Holst, Antonio Caldara and Lili Boulanger? The two musicians and their partners in Camerata Bern explore the image of woman through ten centuries of music: the figure of the Virgin Mary - among other works, the triptych Magnificat - Ave Maria - Stabat Mater (1967/68) by Frank Martin, an unclassifiable composer whom both artists venerate - but also Mary Magdalene, in pieces by Caldara and Kurtág. The Saint, the Mother, the Whore... The expression of two women musicians of today, a journey full of meaning and a sensory exploration featuring solos, duets, quartets and works for large orchestra.
