Nina Simone does one of her most famous protest songs, "Mississippi Goddam," in Holland in 1965. The civil rights era anthem, first performed in March 1964, is a response to the 16th Street Baptist Church bombing and the murder of Medgar Evers. There's real tension in the jaunty music and troubled lyrics. "Alabama's gotten me so upset, Tennessee made me lose my rest, And everybody knows about Mississippi Goddam."
