Los Temerarios were five young guys from the State of Tabasco, Mexico, who in 1965 decided they were ready to conquer Mexico City with their Beatles suits and wild beat music. They recorded three albums, one on Regis (Rock, Rock, Rock, 1965) and two on Son Art (La catedral de Winchester, 1966, and this eponymous compilation from 1967). They had a short-lived radio hit with the Beatlesque Vas a perder a esa chica and later on started other projects.
