In April 2012 Roumagnac gets from the directors of L!Elysée (theatre – Lyon, France) to proceed the whitening of their whole theatre (stage + audience space). Through this whitening Roumagnac aims to «"reveal"» the illusion of the disappearence of the theatre (the space) used as conventional black box. Before the painting starts, Roumagnac proposes photographer Aurélie Pétrel to join and to shoot the painting process from its beginning to its end. They both agree about the potential of this visual material and therefore plan to proceed on a first collaborative installation and dialogue in between their respective media. In deed they decide to use the photographies shot by Petrel as a base for an installation titled Theâtre which is, after negociation with the directors of the site, scheduled in situ for the coming September. The installation would consist in printing (scale 1/1) three of Petrel!s images on transparent plexiglas and to set them up vertically ,thanks to a solid wooden frame, close to the walls (30/40 cm) they represent (on the image": walls in the whitening process). The project aims to invite the usual spectator of the theatre to perceive a doubletriggered exposure (theatre + photography) through an experience of duration (in their works the two artists share the same following question": which present(s) can the theatre and the photography expose/represent " still?). In August 2012, after a serie of fundamental desagreements about the procedure of installation between Roumagnac and the theatre administrators, the project is cancelled. As a strict in situ project, it is consequently definitely condamned to remain an «"unrealized project"». After and due to this cancellation, Roumagnac and Pétrel decide then to propose their project Theâtre! to the Agency for Unrealized Projects.
