My recent foray into music from Blaxploitation films was inspired by a formerly homeless man named Marcos Powell. Marcos is a contributing writer to the Curbside Chronicle, a monthly magazine published to benefit Oklahoma City’s homeless population. The vendors, all homeless or low-income — and unfailingly positive and polite — are regulars on the streets of downtown, selling the latest edition for a $2 donation. In the current issue, Marcos pays homage to the often campy, always groovy Blaxploitation movement of the early to mid-’70s. Though some, including the NAACP, claimed the movies perpetuated negative black stereotypes, they “inspired filmmakers like John Singleton and Spike Lee.” You never know what you’ll learn from a guy like Marcos.
