Purpose: The aim of this chapter is to theorize and describe the main characteristics of the social construction of the policy of electro-amplified popular music (EAPM) in the French context. Design/methodology/approach: To explain the signification and the institutionalization of EAPM through the conflict and mediation between two modes of legitimation of the rebellion and recognition of identity: deliberative rationality and verbalization of protest, on the one hand, and "musicalization" of revolt and globalization of the rebellious feeling attitude, on the other hand.
