Donald Glover, aka Childish Gambino, celebrated the Fourth of July by releasing a new mixtape called Royalty. This new tape really shows of the strides he has taken since his freshman album, Camp, as a rapper and a rapper who can snag big-time guests. The hour long affair features high-profile appearances from hip hop heavy-weights like Bun B, RZA and Ghostface Killa; hip hop up-and-comers like Danny Brown, Ab-Soul, and Kilo Kish; and, um, Tina Fey, who closes the tape with a verse of her own. And it’s as that less-than-likely, last-but-not-least guest that she has managed to steal the show. Because who says rap can’t be funny?
