The Swiss-Ecuadorian sibling duo of Estevan and Alejandro Gutiérrez—have announced their new album Los Ojos Del Cóndor , out September 25 on Easy Eye Sound. Produced by Dan Auerbach of The Black Keys at his Easy Eye Sound studio in Nashville, the 10-track album draws the duo's cinematic guitar work more directly toward their South American roots, trading the wide-open spaces of the American West for the rhythms and textures of the Andes – a vivid new palette of sounds and influences from the continent that shaped them.
