Members: Antonio Romero Monge Rafael Ruíz Los del Rio (Spanish for those from the River, referring to the Guadalquivir or the Guadaira) is a Spanish music duo comprised of musicians Antonio Romero Monge and Rafael Ruiz. They are originally from the city section of Dos Hermanas in Seville. As a duo, Romero and Ruiz have been a consistent, and persistent, act since the early 1960s. They had achieved considerable attention in southern Spain by the time "Macarena" was written, but not without experiencing some hardship beforehand.
