Punk is often regarded as a subculture that is essentially based on the principles of authenticity. The inauthenticity of the immigrant punk to the available styles and genres of popular music and its impurity in relation to particular folk traditions translates the dislocation of the immigrant subject. As an example of new postmodern authenticity, this chapter analyses the question of selfhood and discusses the way it is represented in immigrant punk. It reviews the argument that associates punk with postmodernism. The chapter introduces a response to the tension between the postmodern attitude and a search for authenticity by the immigrant punks. This response is analysed in relation to the rebellious, revolutionary and transformative potential of punk, so crucial to its cultural identity. The chapter concludes by situating the inauthenticity of immigrant punk in a theoretical framework of the postmodern subject.
