 In the French chanson field, irrigated by a strong poetry tradition, such singer-songwriters as Léo Ferré or Serge Gainsbourg made their own use of spoken word over rock or symphonic music from the very beginning of the 1970s.Although these probably did not have a direct influence on rap's development in the African-American cultural sphere, they paved the way for acceptance of spoken word music in the media market, as well as providing a broader backdrop, in a range of cultural contexts distinct from that of the African American experience, upon which rapping could later be grafted.With the decline of disco in the early 1980s rap became a new form of expression.
