La Revolución de Emiliano Zapata is a Mexican rock band that broke sales records in Europe and Mexico with their hit song 'Nasty Sex' at the height of the counterculture era of the early 1970s. Breaking ties with their original concept as the hippie era waned worldwide by the mid-1970s, they continued actively interpreting romantic ballads with considerable success. In 2009, they returned as a rock act.
