Soul/Funk music and Civil Rights

Sometimes while discussing Soul and Funk music we tend to forget that the music did not exist in a vacuum. The music was a product of the existing environment of the time in which the musicians who created it lived... If the period of Soul is roughly defined as 1955 - 1970. It very much parallels the Civil Rights movement. I would maintain that Soul music and the Civil Rights movement had a duel impact on each other. One example that I can think of right off the top of my head is A Change Is Gonna Come by Sam Cooke. Another would be the image of Aretha Frankin singing at the funeral of Dr. King. When Chuck Berry announces to the world that he is in fact "A Brown Eyed Handsome Man" in 1956, he is telling the listener that he is a Black man, who is here to stay. Just a few short years later Berry Gordy took Chuck's notion and turned it in to a record company that would quietly achieve all of the objectives of the American Civil Rights movement while never uttering a single sentence about it !! Stax records was perhaps the ultimate, as a unique black/white partnership created gut bucket raw Soul music for the masses. I would also maintain that Funk music and the "Black Pride" movement had a duel impact on each other. Some example that I can think of right off the top of my head is recalling for the first time seeing a Black man (JimiHendrix) wearing an Afro, hearing the inspirational lyrics of Earth Wind and Fire. The connection between "the music, the people and the one", was never more clear.
