This article studies the presence of the concepts of dominator/oppressor and dominated/oppressed as contextual notions where discursive representations of the rock band Mapuche Peumayen are observed. With that in mind, it's my objective to value this musical group as a political subject that in turn constitutes a discursive fact. This study aims to observe these concepts from discursiveness, visibilizing the position of cultural and political claim developed by this musical group in their musical work. Methodologically, the model of the Critical Complex Analysis of the Discourse is used, using the lyrics of the songs of their first disc as the base of analysis.
