Joseph performs a recital with mezzo-soprano Sophie Rennert at the Pierre Boulez Saal, Berlin.

On the operatic stage, Austrian mezzo­soprano Sophie Rennert is acclaimed for her portrayals of Baroque heroines—including her celebrated debut as Galatea in the staged production of Handel’s Aci, Galatea e Polifemo in November 2023 at the Pierre Boulez Saal. Together with pianist Joseph Middleton, she now gives voice to her other great passion: the lied repertoire. In addition to a selection of works by Franz Schubert, the duo performs Mahler’s moving Rückert Songs.
