Piedra Roja was a music festival in Chile noted as an expression of the hippie counterculture in South America.
[1] Following the success of Woodstock, a similar music festival was held in Chile between 10 and 12 October 1970 in the eastern area of Santiago.
Similarly to Woodstock, chaos marked the festival, involving problems with sound, drugs and delinquency.
It also showed the increasing social tension that would end in the 1973 Chilean coup d'état.
[citation needed] The festival was organized by Jorge Gómez Ainslie and is the topic of the first chapter of Psychedelic Chile: youth, counterculture, and politics on the road to socialism and dictatorship.
