“More towards McLuhan than Rap Brown”

“Sly definitely has something to say. He stands strong among the young innovators of today, the young revolutionaries. But Sly’s revolution is more towards Marshall McLuhan than, say, Rap Brown. His field is communication, the electromagnetic bands, a plethora of electronic instruments, amplifiers, between microphones, headphones, dance hall or audience or recording studio, where he stands with the engineer mixing his tapes at the Columbia Studios in New York.”
David Henderson, “Sly & the Family Stone,” Crawdaddy! #18, 1971
