The reservoir dramatically transforms the landscape, its tranquil waters creating an immense mirror.
Conceptually, the piece is built upon reflection. An echo, understood as the return of a sound wave after striking a distant surface, can only exist if there is something to reflect it. In the words of Boa Mistura, "the proposal translates this idea to the visual plane: the dam's retaining wall becomes the support for a work that paints the water and is completed by taking advantage of its reflective properties."

The intervention requires constant balance. The line of symmetry must remain stable for the message to be revealed, creating an imaginary line that concentrates the poetic tension of the work. "The installation reacts to fluctuations in the reservoir's water level: it disappears when the water rises and is interrupted when it falls." “It’s a living, ever-changing piece, visible or unintelligible depending on the intensity of the rain; a witness to the times we live in, a live visualization of our relationship with the environment,” Boa Mistura explains.
As a result of this approach, Boa Mistura created ECHO with a dual perception, as both image and question. “It reflects to us the impact of our actions and invites us to consider the echo we produce in the world we inhabit. The landscape we take for granted in our daily routine reappears under a renewed gaze. The work proposes re-establishing a connection: to approach again, with humility, a territory that is not just our surroundings, but our home.”
