La Revolución de Emiliano Zapata (meaning "Emiliano Zapata's Revolution" in English) 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.
The band has gone through numerous musical and lineup changes, and throughout its existence the only member that has always been in the band is its founder, Javier Martín del Campo.
