Popular music plays important roles in two related films portraying Brazilian slum life. Based on a 1953 play by Vinícius de Morais, Marcel Camus's 1959 film Orfeu Negro, and a 1999 feature by Brazilian director Carlos Diegues titled Orfeu, augment traditional samba styles with bossa nova and rap, respectively. Interpreting musical style as allegorical texts within fictive landscapes, this paper examines conflation and conflict among musical meanings, Brazilian social histories, and discursive identities marking the twentieth century. Broad aspects of Brazilian political and socio-cultural development are implicated, such as authoritarianism, the politics and sociology of race, technological advances, mass media, and modes of modernisation. Here, bossa nova and rap engage society through reflexive and generative interpretations within a narrative designed to illustrate connections between processes of innovative, trans-national cultural production, myths of national identity, social change, and the powerful role of popular music in film.
