 The Rock y Ruedas (Rock and Wheels) festival had originally begun as "nothing more than a series of auto races".The organizers suggested that rock music should be included to have a "Noche Mexicana" the night before the event.As many bands were hired to participate, a rock festival was organized to promote the auto race ‒ but instead turned into a "Mexican Woodstock" with a huge number of Mexican rock bands such as Los Dug Dug's, El Epilogo, La Division Del Norte, Tequila, Peace and Love, El Ritual and so many more playing to a crowd of over 300,000 people for two days.
