"Classic Man," the 2015 debut single from Nigerian-American MC Jidenna, caught everyone off guard. The song found him teetering between rapping and singing about elegance, politeness and Nat "King" Cole, and the melody felt irresistible. Then there's the look: He rocks thrift-wear tailored to a T. The song eventually went double platinum and earned a Grammy nomination. Jidenna followed it with a few more club bangers before releasing his debut album, The Chief, earlier this year. A tribute to his father, a Nigerian chief, the record is peppered with African rhythms and themes.
