Sediment is a series of abstract narrations which combine the generative visuals of Lali Barrière with the static music of Ferran Fages, with a clearly minimalist approach. The visuals use a single graphic element: the line, horizontal or vertical. The lines’ change of color, often masked by its slowness, is perceived as motion and generates a landscape in continuous transformation. The sound materials are sustained tones, sympathetic resonances and overtones from the zither strings. The use of alternative tunings, specific for each piece, allows to generate a sound environment made of suspended clusters. A dialogue between music and visuals flows on a substrate of slow tempo.
