Louisville's Bryson Tiller rocketed out of obscurity in 2014, becoming R&B's hottest new voice. All it took was “Don't”, a slow jam about a girl who deserves better from her man, which immediately went viral and got him a coveted Drake co-sign. Like the OVO head, Tiller switches seamlessly from rapping to singing, often in the same verse. But Tiller ultimately is an R&B purist, known for flipping sultry vintage classics and updating them for the current day; check out “Exchange”, a sexy fantasy about an old flame that samples K. P. & Envyi's 1998 jam “Swing My Way”.
