Du long du long was inspired by the surrounding landscape, particularly the Lachine Rapids. The artwork is composed of five metal plates laid flat on slightly inclined crosspieces. The first plate is placed near four others that unfurl horizontally in a fan shape. These plates, overlapping slightly, evoke the agitation of the current flowing over obstacles and changes of level in the riverbed. In the centre of these steel planes, the artist has shaped the material significantly, cutting the metal and creating, through folds, twists, and assemblage, a broken path. The reliefs, hollows, bands, and curves suggest the undulation of water and its streaming around disturbances.

This sculpture is integrated ideally with the environment. It is situated almost at ground level and is placed longitudinally on the axis of Lake St. Louis, so that it has a planned “east,” “west,” “north” and “south” that cannot be inverted.

The artwork was created for the first Lachine, Carrefour de l’Art et de l’Industrie sculpture symposium in the summer of 1985. Organized by the Société de diffusion internationale et de placement sur œuvres d’art (Sodip-Art), the event brought together eight sculptors each of whom produced a monumental sculpture on site as the public watched.
