Exactly 75 years ago, on 28 August 1930, Britain's most remote community disappeared. The last 36 St Kildans were evacuated from their islands, 110 miles west of the Scottish mainland, after 5,000 years of habitation. From the noises of the place - wind, birds, the Atlantic, memories of the last islanders, his own poetry - Scottish poet Kenneth Steven weaves a piece of tweed in sound to commemorate life and death in St Kilda.
