The play is an aerial river of sounds that crosses the city of Guadalajara, the sound in the air is a melodic interpretation of the chemical composition of water, the numeric digits of the physical composition of this vital liquid are transformed into Hertz and turned into a musical piece, this sound is projected by air megaphone, by means of loudspeakers. The light aircraft goes over the path of the river San Juan de Dios that is nowadays hidden by urban processes; this is piping underground the city. Formally the sound action explores the aesthetic possibilities in the duality between sound and visuals, the real object and its representation, the underground and the underheaven, different narratives, but not antagonistic.

The project also includes alternate activities such as live performance and photographic performance, consecutive actions that will create a closer connection between the public and the work of art.
