We are happy to welcome artist Jacques Grison for the first time. Coming from documentary photography, he unveils an original work at the gallery, putting to the test an archeology of memory and perception. Watching for the resurgences of runoff, crossing surfaces promised to disappear, he enters the most unstable materials, as if to bring to light what "stirs" and is formed behind the real world. It turns out here that, if it is the gaze that makes the image, it is well after the rain that the apparitions appear on the excavation fields.
