After the 1968 Mexican student movements ended in the Tlatelolco massacre in Mexico City, a native hippie movement known as jipitecas grew in its wake and expanded to the entire country as well as parts of the US and Central America. By 1969, a new wave of Mexican rock music began to emerge, fusing Mexican and foreign music with images of political protest. This movement was called La Onda Chicana, culminating in a two-day "Mexican Woodstock" known as (Avándaro) which attracted ca. 300,000 people in September 1971.
