Queen Latifah anointed herself as the princess of the Flavor Unit posse in the late-'80s as she kicked smart and assertive raps over music made by Mark The 45 King. 1989's All Hail the Queen stands as an imperious release, complete with a feminist workout with Monie Love, while '91's Nature Of a Sista brought in beats from fellow New Jersey natives Naughty by Nature, and '93's Black Reign produced the hit “U.N.I.T.Y." As Latifah moved into the acting world, she also expanded her musical ambit with a sideline performing jazz standards.
