Martha Argerich and Itzhak Perlman. What a combination! Each of them has been recognised for more than 50 years as a supreme musician, but this is their first studio album together. Their programme comprises Bach (Sonata for Violin and Piano No. 4 in C minor, BWV 1017, whose lilting opening movement became the sublime ‘Erbarme dich’ from St Matthew Passion), Brahms (Sonatensatz in C minor, Op. posth.) and Schumann (Fantasiestücke, Op. 73 and the Violin Sonata No 1 in A minor, Op 105).
