A sound is born from the root of the earth. Those are the voices that sing for the animas of Purgatory. Every year for centuries los Cantadores de Arbejales, in the misty mountains of the island of Gran Canaria, fulfill a ritual cycle, a sacred task for them, "the request of the alms" and pray singing for the Souls. Tradition, mystery and fabulation cross paths in the midst of exuberant nature.
