Solo piano. Nubes (clouds in Spanish) consists of two movements played without interruption. The first, Cumulus, is a play of sonorities based on a fixed intervallic structure. In the distance, one can hear intimations of a storm. The second movement, Nimbus, erupts powerfully; the play of intervals expands. Wind, rain and electrical discharges grow from a single nucleus and come together creating an apocalyptic climate. Suddenly the sky clears and the storm dies. Nubes II concludes the cycle..
