If ever there was a composer who embodied America, its wide-open spaces and pioneering spirit, then it must be Aaron Copland, even if his Socialist sympathies made him a target of the McCarthyite witch-hunts of the 1950s. This concert offers the chance to explore his expansive soundscapes with accessible, insightful introductions from broadcaster Stephen Johnson and idiomatic performances from conductor John Wilson, whose recordings of Copland’s music with the BBC Philharmonic have been widely praised.
