But other styles began to emerge during the 1970s. One of the more successful styles was "outlaw country", a type of music blending the traditional and honky tonk sounds of country music with rock and blues music, and mixed with the anger of an alienated subculture of the nation during the period. The leaders of the movement were Waylon Jennings and Willie Nelson, although others associated with the movement were David Allan Coe, Jessi Colter, Tompall Glaser, Gary Stewart and Billy Joe Shaver. The efforts of Jennings, Nelson Colter and Glaser were encapsulated in the 1976 album "Wanted! The Outlaws".
