Dmitri Shostakovich: Symphony No. 5. Music has sometimes reflected, and at other times challenged repressive ideologies. Shostakovich abandoned the premiere of his challenging 4th symphony for fear of reprisals from the Stalinist government. His triumphant 5th Symphony was next, and the authorities were pleased. To this day the 5th is Shostakovich's most popular symphony. What is its message? What does "political music" mean today?
