Ralph Vaughan Williams (first name pronounced Rafe, FWIW) wrote some of the most beautiful music ever composed: the Fantasias, Serenade to Music and the 5th Symphony are some examples. But, like many composures, he was deeply affected by the world wars and they inspired music of a more agitated character, like the 4th Symphony.
On CD, from the Previn/Vaughn Williams box.
Even at his most distressed RVW's music is perfectly listenable, and contrasted with moments of pastoral stillness. And you can't go wrong the Andre Previn's Vaughan Williams from the 70s, perhaps that best stuff he has ever done.
