Los Sleepers emerged in Mexico City in the early 1960s, blending rock and roll with balada to create a distinctive sound. The original lineup featured Arturo Aller Covarrubias (vocals and rhythm guitar), Willy Vallejo (drums), Rafael Miranda (lead guitar), and Abraham Oceransky (bass). Their 1961 debut album produced hits like "Hermanita," "Ojos de Araña," and "Papacito Frío," showcasing both original compositions and innovative arrangements. In 1963, they released "Al Ritmo de la Lluvia," further solidifying their place in Mexico's rock scene. Their track "Zombie," penned by Oceransky, has been covered by contemporary bands, attesting to their enduring influence.
