In the three years since her seminal album “A Seat at the Table”, Solange has broadened her artistic reach, expanding her work to museum installations, unconventional live performances, and striking videos. With her fourth album, “When I Get Home”, the singer continues to push her vision forward with an exploration of roots and their lifelong influence. In Solange’s case, that’s the culturally rich Houston of her childhood. Some will know these references – candy paint, the late legend DJ Screw – via the city’s mid-aughts hip-hop explosion, but through Solange’s lens, these same touchstones are elevated to high art.
