There aren't any current black artist that are high on the charts to perform that aren't either currently on tour or something that nature. Only black artist I can see performin are drake and Kanye. Rih and bey are currently on tour. Correct me if I'm wrong but I can't think of any other people and you know how billboard is. If you not in the top 40 on the hot 100, then they usually aren't checking for you. For instance Bryson tiller and j Cole has sold more than Jason derulo album wise but I bet they call Jason before the other two. Could at least got Chris brown though .
