As night fell, a ten-year-old boy strolled through his hometown of León Guzmán, Mexico, a small community with approximately 3,000 inhabitants. A 12m truck followed him, casting light upon him and his path. Subwoofers mounted on the truck (Approx. 4000 Watt) enhanced the sound of his steps. The sound was generated by microphones hidden in the boy's shoes and sent wireless to the sound system on the truck. After thirty minutes, both the sound and the light faded out and the boy vanished.

The performance was presented without previous announcement.
