This research is the result of a study of the figure and work of brazilian composer Adriana Calcanhotto. Singer, lyricist and composer, her work has been characterized mainly by transit at the borders between the classical and popular, the mass culture and avant-garde art, with achievements ranging from poems set to music by Carlos Drummond de Andrade, Waly Solomão, Antonio Cicero, Ferreira Gullar, Mário de Sá-Carneiro, Haroldo and Augusto de Campos, and wear the Parangolés of Hélio Oiticica (artists related to avant-garde art), recording songs related to tradition and kistch s corny, consumed largely by the means of mass communication. The movement of this artist makes us think immediately in the discussion launched by José Miguel Wisnik known in his essay A Gaia Ciência, in which the essayist and songwriter of brazilian popular music advocates as legitimate space for building knowledge. Thus, I reflected of the work of Adriana from that perspective, signaling this playful space that the artist builds, able to articulate knowledge and sensitivities. To this end, I analyze the lyrics to songs, costumes, sets and repertoires show, speaking to the press etc. In a second step, I intend to reflect on the paradoxical process (pointed by Antoine Compagnon) of desecration of art and the modern fetishization of the author, and which increases in the contemporary scene, in which the artist goes to work on building an image (an artistic persona), transforming their bodies also artistic support. In this scenario, constantly traversed by the media and by exposure, in which notions of public and private essence and appearance, are confused, clouds are also the boundaries between art and life.
