In an act of defiance during World War Two, starving musicians in the besieged city of Leningrad performed Shostakovich's new Seventh Symphony. The piece was composed especially for the city, which had been cut off and surrounded by invading Nazi troops. During the siege an estimated one million civilians died from starvation, exposure, and the bombardment by German forces. Hear archive recordings of Ksenia Matus who played the oboe in the orchestra, and hear from Sarah Quigley, the author of a novel about Shostakovich's Seventh Symphony. Dina Newman reports.
