Watch FMovies. The documentary Black Rio! Black Power! looks at the influence of the Black Rio movement on culture, society and the struggle for racial justice in Rio de Janeiro and Brazil between the 1970s and 1980s. The film shows the movement's impact on music and on the direction of politics and the black movement during the period of re-democratization, influencing genres such as hip-hop and funk, and the affirmative stance of the younger generations, who perpetuate the black pride and aesthetic appreciation spread by Black Rio 50 years ago.
