As the collective euphoria of the '60s gave way to the jaded hangover of the '70s, Sly & The Family Stone kept a constant groove. “I Cannot Make It” remains a perfect fusion of soul music's grit and rock 'n' roll's power, while “You're the One, Pt. 1 & 2” is a stomping slice of self-empowerment. Even the early-'80s jam “Same Thing” finds Sly's melodic gift for funk music intact.
