At the Discretion of River was inspired by Chinese traditional painting, most notably the concepts of emptiness and fullness. Islands of materials — plains, mountains, and rivers — are painted separately and connected by emptiness, a buffer zone consisting of "nothing." The interest resides in the interdependence between emptiness and fullness : emptiness, being constantly identical and homogenous, completely depends on the context built by fullness, while fullness owes all of its poetry and balance to the context created by emptiness.
The audiovisual version of At the Discretion of River was performed at the Wilder's Espace Bleu on May 9, 2021. It is interpreted by Jean-François Laporte.
