It took her an hour to write “Mississippi Goddam.” A freewheeling cri de coeur based on the place names of oppression, the song has a jaunty tune that makes an ironic contrast with words—“Alabama’s got me so upset, Tennessee made me lose my rest”—that arose from injustices so familiar they hardly needed to be stated: “And everybody knows about Mississippi, goddam!” Still, Simone spelled them out. She mocked stereotypical insults (“Too damn lazy!”), government promises (“Desegregation / Mass participation”), and, above all, the continuing admonition of public leaders to “Go slow,” a line that prompted her backup musicians to call out repeatedly, as punctuation, “Too slow!” It wasn’t “We Shall Overcome” or “Blowin’ in the Wind”: Simone had little feeling for the Biblically inflected uplift that defined the anthems of the era. It’s a song about a movement nearly out of patience by a woman who never had very much to begin with, and who had little hope for the American future: “Oh but this whole country is full of lies,” she sang. “You’re all gonna die and die like flies.”
