While much social science literature has analyzed the cultural bases of social movement, activity, and the content of cultural production by social movements, relatively little has been written about the concrete social relations within which social movements do culture.

A contrast between the how the People's Songsters Movement of the 1930s and 1940s and the Civil Rights Movement of the 1960s used American folk music illustrates how variation in these dimensions affects the effects that cultural production had on social movement outcomes.Keywords Social movements .
