After the important commission that gave rise to this series, a work with a marked documentary component - dedicated to the Instituto Superior Técnico, 1993-1994 - Augusto Alves da Silva develops another commissioned project, this time focusing on the Companhia Nacional de Bailado (CNB) [National Ballet Company]. The monitoring of the Company's activities, carried out during 2001 and again in 2002, had two distinct phases, which originated the exhibitions and respective publications: CNB 2001, Camões Institute in Paris, 2001 and 2, Centro Português de Fotografia [Portuguese Photography Centre], Porto, 2003.

As part of the first phase of this project, Untitled (CNB 2001) belongs to a series that was selected from a body of work for commercial purposes. However, these images frustrate the convention normally associated with the universe of references created to promote the ballet, connoted with the beauty, delicacy and elegance of gestures and movements. Intentionally avoiding the moment of the show, the artist chooses to highlight the space behind the scenes. By revealing what is inaccessible to the viewer, the series includes images that oscillate between the staging of the front portrait, the capture of moments and images of empty spaces, being this work included in this third category. The image of the unoccupied dressing room is, in this composition, oriented by diagonal lines, where the illumination of the enclosed space is accentuated by mirrors reflecting the electric light and highlighting the absence of the dancers. In the whole series Augusto Alves da Silva underlines the artificial dimension of the show, and the technical precision, so many times highlighted in the artist's work, is here applied harshly in an approach to the sociological study of a micro-cosmos, ambiguously defined between the document and the subjectivity of the artist.
