Book excerpt: Building on their studies of sixties culture and theory of cognitive praxis, Ron Eyerman and Andrew Jamison examine the mobilization of cultural traditions and formulation of new collective identities through the music of activism. They combine a sophisticated theoretical argument with historical-empirical studies of nineteenth-century populists and twentieth-century labour and ethnic movements, focusing on the interrelations between music and social movements in the United States and the transfer of those experiences to Europe. Specific chapters examine folk and country music, black music, music of the 1960s movements, and music of the Swedish progressive movement. This highly readable book is among the first to link the political sociology of social movements to cultural theory.
