In Chicago, the musicians juxtapose Beethoven’s “Ghost Trio” in D-major Op. 70/1 with Currier’s “Ghost Trio” – in addition to violin sonatas by Mozart, Poulenc and Ravel. Mutter and Orkis have not only been performing together in the world’s leading concert halls since 1988, they have also produced numerous CDs for the label Deutsche Grammophon. Their joint recording of Beethoven’s sonatas for piano and violin won a Grammy Award, for example. In commemoration of the silver jubilee of the two exceptional musicians, a double CD with samples of the two exceptional musicians’ repertoire was released in 2014.
