Andris Nelsons and the BSO conclude their award-winning decade-long Shostakovich project by presenting their acclaimed Shostakovich symphony cycle. Benefiting from the superb audio quality achieved in the exceptional acoustic of Boston's symphony hall, Yo-Yo Ma gives inspired performances of the two cello concertos. The inventive first was written for another friend, Mstislav Rostropovich, a famously demanding piece that was an early landmark in Ma's own career. The far more introspective second was the composer's 60th-birthday present to himself.
