Barão Vermelho: Por que a gente é assim?

A detailed chronicle of the famous 1969 tour of the United States by the British rock band The Rolling Stones, which culminated with the disastrous and tragic concert held on December 6 at the Altamont Speedway Free Festival, an event of historical significance, as it marked the end of an era: the generation of peace and love suddenly became the generation of disillusionment.

An intimate look at the Woodstock Music & Art Festival held in Bethel, NY in 1969, from preparation through cleanup, with historic access to insiders, blistering concert footage, and portraits of the concertgoers; negative and positive aspects are shown, from drug use by performers to naked fans sliding in the mud, from the collapse of the fences by the unexpected hordes to the surreal arrival of National Guard helicopters with food and medical assistance for the impromptu city of 500,000.
