Guillaume Dufay was one of the most famous and successful composers of the mid 15th century. Born in Cambrai in what is now northern France, he spent most of his career touring Europe, working in some of the most important and influential centres of his day. He found himself in the middle of many of the major political struggles comfronting the 15th century which inevitably had a profound impact both on his life and music.
