Lena Horne’s song Now! was banned from the airwaves in the US, because its call for civil rights and racial equality was deemed in danger of starting a riot. Which, to quote Toni Morrison who had her book banned for the same reason, “How powerful is that!” Lena gave the song to Santiago Alvarez, who set it to some of the most unflinching images of racist violence. The result is a damning indictment of American society, a lesson in history, a music video, a piece of Cuban propaganda, and a moving and powerful call for equality, all rolled into one. Defying the labels of genre, it mixes art and activism in a manner both beautiful and brutal.
