The Funkadelic song "One Nation Under A Groove" (1978) is about the challenges that Blacks overcame during the 1960s civil rights movement, and it includes an exhortation for Blacks in the 1970s to capitalize on the new "social and political opportunities" that had become available in the 1970s. The Isley Brothers song "Fight the Power" (1975) has a political message. Parliament's song "Chocolate City" (1975) metaphorically refers to Washington D.C. and other US cities that have a mainly Black population, and it draws attention to the potential power that Black voters wield and suggests that a Black President be considered in the future.
