Between May and September 2021 Effi & Amir, Suleiman, Ahmed, Mohamed, Pacifique, Louis, Joël, Musa and Sayed collaborated at La CENTRALE for contemporary art, Brussels. The re-appropriation of the space and the inversement of guest-host role were at the core of the process. Developed in close collaboration with the artist duo Effi & Amir the publication of Hypothèse d’une porte is both a trace and a retrospective of the project.
