With his weary, yearning vocals, this London crooner and guitarist has the power to draw a deep sense of nostalgia from even the youngest listener. There's something in those honeyed pipes—recalling soul men like Bill Withers and Otis Redding—that carry his tunes into sepia-toned reverie. After working as a session guitarist, Kiwanuka went solo, toured with Adele, and eventually released his debut album, Home Again, in 2012. Since that promising start, he's proven himself quite the retro-inspired polymath, folding his voice and six strings into a smooth mix of soul, folk and jazz.
