Shout out to creative minds collaborating to produce dope music; I appreciate that so much. Solange Knowles brought Dev Hynes, Moses Sumney & KING on stage during her set at the FyF Fest to perform a cover of Nina Simone's "Young, Gifted and Black." Above is a video of their rehearsal for this performance and they knocked it out of the park. They all have beautiful voices and they harmonize amazingly with each other. Check out the dope video above.
