The work and career of the Australian band Midnight Oil show the social and political dimensions of the contemporary popular music. Backed by more than one hundred songs, nearly two thousand concerts and dozens of acts of vindication and solidarity, Midnight Oil offered a critical and ideological interpretation of the political and social evolution of Australia. In perspective, their career throws light over the extend of a social and political speech vertebrated from the sphere of urban popular culture in an advanced capitalist society. In fact, through a critical surveillance of Public Management, they visualized the possibilities of rock music as an instrument and a vehicle for participating in politics, a mean of resistance and dissidence.
