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
