There’s a dark and edgy feel in Summer Walker’s songs thanks to the moody trap production style and the charged emotions that often flow between the R&B diva and superstar guests like Drake and Usher. Yet the Atlanta singer/songwriter’s love of ‘90s neo-soul means that plenty of light shines through the darkness, too. Delivered in a manner both sultry and sly, her lyrics combine witty frankness and undisguised vulnerability. On tracks like “Girls Need Love” and “Playing Games,” she lays bare everything that’s on her mind and in her heart even as her deft handling of melody and groove reveal a more playful side.
