Though Sly & The Family Stone's soul-infused music always conveyed unbridled joy, under their uplifting rhythms were critical commentaries on the state of America in the '60s and '70s. “Luv n' Haight” and “Thank You for Talkin' to Me, Africa” are funky and jubilant, yet also uncanny portraits of a country in upheaval. “Don't Call Me N****r, Whitey” sums up the group's cutting views on racial strife in one nasty, intoxicating groove.
