The Brazilian artist Waltercio Caldas began his career in the late 1960s and his distinctive performance was very important to the artistic debate in the following years. His work is remarkable notably for two reasons. First of all, it contributed to redefine the experimental sense of the Brazilian art and its relation with the artistic environment of that period. Secondly, it introduced the concept of contemporaneity which has not been used so efficiently nowadays. The sensation of the exhaustion of the modern project and the contemporary contradictions empowered Waltercio of a critical consciousness about the place and role of his artworks in the art scene. If, at the beginning, Waltercio s main focus was to reach art efficiency by questioning works at institutions and market levels, later on the situation became more complex. From that moment onwards, the form should be thought without telos and place in the contemporary cultural life, since it was part of a specific moment of the art system and, specially, the market. In order to face this situation of generalized spectacularization, Waltercio explores the presence of the artworks and their aesthetic legitimacy. This critical study intends to reflect about the development of a work in progress from the 1970s to 2010s. Besides, this research will emphasize the poetic strategies that strongly influence his conceptual work and its contemporaneity today.
