Solange and Dev Hynes bka Blood Orange were guests on last night's episode of Late Night with Jimmy Fallon, performing her single "Losing You." They wore complementary shades of emerald and sunshine and, along with the rest of the band and two back-up singers, did a synchronized back-and-forth bop. The appearance is a sort-of kick off for Solange's short tour of the US and Europe, which launches tonight at New York's Bowery Ballroom. Tickets are sold out.
