The artist Cildo Meireles in search of the sound of Brazil's main water basins in order to construct the sound sculpture Rio:Oir (River:Hear) created from the play on words and concepts. From Foz do Iguaçu to the Pororoca of Macapá, from the Águas Emendadas Park to the mouth of the São Francisco river, and later, in a studio, gathering the pieces and matching them to the cacophony of residual waters and human laughter. The documentary "Listening to the River" reveals the artist's simplicity, the relation of region's inhabitants with water, and it enhances our perception between sound and image.
