This list was set to be 20 artists long, but then we had British MC Lady Leshurr on our radio show, The LargeUp Sessions, Thursday night. A native of Birmingham, England with roots in the island of St. Kitts, Leshurr’s been making waves in the U.K. for a few years now, but, as we learned the other night, her profile is increasingly international. She’s spent the last few weeks on a whirlwind tour of U.S. studios, recording with LargeUp-approved beatmakers including JayCeeOh and Geko Jones. Until those tracks see the light, familiarize yourself with “Upset,” which showcases her Missy-like flows over a beat sampling Peter Tosh’s classic bumboclaat tirade. —Jesse Serwer
