In 1914 the American poet Robert Frost published his collection 'North of Boston'. It was hailed as 'one of the most revolutionary books of modern times' by the English poet Edward Thomas. Matthew Hollis, who has written about the friendship between the two writers, is joined by Frost's biographer Jay Parini to discuss the poet. This programme presented by Matthew Sweet, was recorded in front of an audience at The Royal College of Music as part of the BBC Proms.
