By now, it’s clear that 21 Savage is great at playing the slasher flick villain. There’s a coldness to his demeanor that we associate with menace. It makes him the ideal partner for Without Warning, a fright-focused tape with Offset and Metro Boomin released on the eve of Halloween. Spookers like “Ghostface Killers” and “Run Up the Racks” are right in his wheelhouse. The surprise comes on “Still Serving,” a drowsy, more soulful alternative to his usual fare that finds him talking shop about gunplay and gang life. With Offset in tow, he trades in horrorcore imagery and aesthetics for something less visceral.

21 Savage and Offset are almost shockingly good together; their styles balance each other out. 21 is no frills, letting his deadpan do most of the talking. Offset is all frills, constantly moving and packing in raps. His gestures are even more effective when he isn’t surrounded by the other Migos, who maneuver in similar ways. On “Still Serving,” Offset’s frantic pacing is the perfect complement for 21’s lifeless delivery. The Offset verse is full of flipping cadences and slant rhymes: “All these wedding bands on like I got 20 wives/I’ma fuck around and let the semi ride/I’ma chop the block up like a samurai/Nigga you done told about a hundred lies.” Sure, 21 tries to rhyme “bosses” with “bosses” five times in his verse, but he raps like he’s peering straight through you.
