The dawn of psychedelic rock in Mexico, ten tracks introducing a worldwide phenomena in the realm of the South American memory. A fascinating voyage led by cultish band La Revolución De Emiliano Zapata and several other nuggets-style combo. Originally released in 1971 the compilation was aptly titled La Onda, referring to a broader cultural and political movement. La Onda Chicana grew rapidly in a few years, culminating in a two days “Mexican Woodstock” known as (Avándaro) which attracted ca. 300,000 people in September 1971.
