While pop groups in Latin America were now singing in English as part of a new trend, the band performed in Spanish on 1972's "Smog". For 1974's "Cambia Cambia", Los Dug Dug's went with a well-groomed, clean look, bucking yet another trend among popular Latin American acts which leaned toward singing in English and wearing long hair and beards. Despite stylistic innovations, the RCA label under which they were working did not expend great effort with publicity and support for the act, and thus their 1975 release, "El Loco", was to be their last work at that time.
