Russian composer Dmitri Shostakovich was one of the greatest musicians of the 20th century. But in 1936, Joseph Stalin attended a performance of Shostakovich's opera, Lady Macbeth of Mtsensk.

The Soviet leader was unimpressed and left early. Days later, the state newspaper Pravda published a scathing review titled 'Muddle instead of music', castigating the music as bourgeois.

Shostakovich was blacklisted from public life, and feared for his safety during Stalin's ongoing purges.

The traditional style of his comeback Symphony No 5 in 1937 was a hit with the authorities, and Shostakovich's reputation was restored. But his true intentions are hugely debated – some experts argue the Fifth Symphony was a cleverly veiled act of dissent.

Fifty years on from the composer's death, his son Maxim Shostakovich unfolds the mystery with Ben Henderson.
