A sequence of poetry and music inspired by the world seen from a great height, the flight of birds and the romance of mountain tops. Musical evocations of mountains by Sibelius, Strauss and Liszt sit with work by Shelley and John Evelyn. Anton Lesser and Lesley Sharp read works by Ted Hughes, Pablo Neruda and J.A. Baker which describe the world of birds in flight, and music by composers including Haydn, J.S. Bach and Richard Strauss evokes the same subject.
