Luis Cosme Gonzalez - Acuarelas for Flute, Viola and Contrabass. Commissioned by Arts Trio, "Acuarelas" is an ensemble of pictures with an independent form and content that are closely related to the development of the production of sound. These pictures are not related to each other except the first and last one. In both cases, two crucial moments of Perseus' myth are represented, of which the iconography enhances the perfect balance of Cellini's sculpture. The piece shows a special emphasis in transparencies, as well as light and shades, as used in watercolor painting.
