[3] This documentary focuses on the work and life of Huichol artist Santos de la Torre, whose paneled mural has been displayed, since its inauguration by former Mexican president Ernesto Zedillo in 1997, at the Palais Royal station.

Echevarría's camera follows the process of Santos de la Torre and his family helping him in the making of a new mural that illustrates the history, mythology and religious practices of the Huichol people and also their pilgrimage to Wirikuta, the sacred place for them where he goes to ask their gods for permission to create his new work.

"[4] Jay Weissberg of Variety celebrated the cinematography of the documentary writing "clouds reflected in puddles, awe-inspiring landscapes, the indescribable warmth of wrinkled faces: All these are lovingly captured via a masterful use of framing and a sophisticated use of focal ranges".

[5] Clarence Tsui from The Hollywood Reporter also wrote "Echevarria’s documentary captures his [Santo's] life and Huichol culture vividly and poetically with some fluid camerawork.

With the whole piece revolving around the de la Torre’s process of making a new mural, Echo of the Mountain resembles a ritual in itself.
