Solange Knowles continues her reign as the mellower, indier sister of Beyonce with her new single (written and produced by Dev Hynes), “Losing You.” The song features Solange issuing a coolly detached plea for her hubby to let her know what the deal is, all set to a retro, melancholy party beat. In the accompanying video, she takes a tour of a South African shanty town with a wardrobe full of high-waisted shorts and garish suits. The single is available through Solange's Soundcloud.
