Kopatchinskaja juxtaposes Hartmann’s Concerto funebre, composed in 1939 to express his indignation at the Nazis’ terror, and the Polyptyque for violin and orchestra that Frank Martin wrote in 1973 for Yehudi Menuhin, a work inspired by six scenes from the Passion of Christ painted by Duccio di Buoninsegna around 1310.

The Kyrie from Machaut’s Messe de Nostre Dame, composed half a century after the altarpiece and heard here in an arrangement for strings, is interspersed between the movements, along with Bach chorales, ‘as an invocation of eternal consolation’. A Polish folksinger interprets the Jewish song ‘Eliyahu hanavi’, which expresses the hope of salvation and which Hartmann quotes in his concerto. Six hundred years of music to ‘make the victims’ voices heard’, says Patricia Kopatchinskaja. The album opens with Kol Nidrei by John Zorn (born 1953), in response to the eponymous prayer spoken by a representative of the Jewish community. A Catholic priest and an Orthodox priest also say a short prayer.
