Composed in a city under siege and blasted through loudspeakers at Hitler’s armies, Shostakovich’s Seventh isn’t just a blockbuster symphony. It shaped the course of history. Now imagine it played with all the energy, power and no-holds-barred passion of the CBSO Youth Orchestra – over 100 of the Midlands’ very finest young musicians. Britten’s Sinfonia da Requiem will make an explosive opening.
