The size and capacity of the Concert Hall enabled the Festival to present full-scale orchestras for the first time, and for many years Simon Rattle brought his City of Birmingham Symphony Orchestra to Snape. There was a strong connection with Russian music: Rostropovich and Richter became frequent visitors, and in 1970 Shostakovich's 14th Symphony, dedicated to Britten, had its first performance outside the USSR at the Concert Hall.[citation needed]
