Alain Altinoglu and the Frankfurt Radio Symphony Orchestra have begun to record the complete symphonies of Shostakovich, starting with his Fourth and Fifth symphonies. Shostakovich dared to express human suffering, passion, fear and catastrophe in his music, but always asking the same nagging question: what is man? In this sense, these two symphonies open with a question — an idea of martyrdom that was to become one of the central ideas of his later symphonies and, of course, of his Lady Macbeth of Mzensk. Both symphonies are dated between 1935-1937 when Shostakovich was in his thirties; this was one of the darkest and most difficult phases of his life, marked as it was by the repercussions of some of his writings and the arrest of many people close to him, including members of his family.
