To straighten out the São Francisco River as if editing a video is to alter not only its visible contours, but also the everyday lives of all those whose livelihoods depend on it. Faced with a river whose course is about to be rerouted, the artist remains attentive to the darkness that envelopes it at nightfall. At the twilight of a course both physical and made of memories, the work creates interventions in the landscape that serve as metaphors for the changes to the river and its various phases.
