When pianist Martha Argerich and violinist Renaud Capuçon gave a recital at the 2022 Aix-en-Provence Easter Festival, their extraordinary rapport was evident to all present. Captured live, their programme included three major works for violin and piano, all in the key of A: 'Schumann's Sonata No. 1 Op. 105', 'Beethoven's Sonata No. 9 Op. 47', 'Kreutzer', and 'Franck's Sonata'.
