Petroc Trelawny presents one of the hottest concerts in the BBC Proms 2008 season, which featured the return of pianist Murray Perahia to the festival after an absence of more than 20 years when he joined the Chicago Symphony Orchestra. His collaborations with conductor Bernard Haitink are always keenly anticipated, and his recordings of Mozart's concertos are world-famous. Haitink also conducts the symphony Shostakovich himself suppressed fearing the wrath of Stalin's regime - it remained unperformed for a quarter of a century.
