Tropicalia introduced two very unusual movements to modern Brazil – antropofagia and concretism. In addition to this was pop music from abroad that helped inaugurate postmodernism in Brazil. In spite of the falling-outs and violence, there is a permanence of tradition in Oswald's antropofagia, who at one point of time conflicted with the idea of Romantic Indianism of the nineteenth century. These ideas were and still are seen in theaters and people's notions that involved a relationship that tied back to a longer history of poetic creations.
