"Si Me Dejan" (If They Leave Me) is a collaboration between Colombian Vallenato sensation, Jorge Celedón, and Vicentico, the former frontman of the Argentinean ska band, Los Fabulosos Cadillacs (The Fabulous Cadillacs).

Always with a light touch, often with full force, Bersuit Vergarabat dishes out social commentary and political activism. "Madre Hay una Sola" is no exception, as Gustavo Cordera apologizes to Mother Nature for the damage done to her by the human race.
