Nina Simone's "To Be Young & Gifted & Black" received a stirring tribute from Solange this weekend at FYF Fest. After some Instagram clips of her performance with Dev Hynes surfaced, Solange has shared rehearsal footage from her performance. In the video, Solange is joined by Dev Hynes, Moses Sumney and King in a remarkable cover of Nina Simone's brilliant ballad. On her Saint Heron blog, Solange described the rehearsal as a "special moment of solidarity and pride, in celebrating our blackness." Check out the video above.
