Metro Boomin brings the best out of 21 Savage—that is, his most savage behavior. He amplifies the horrors of 21’s dead-eyed stories the way John Carpenter amplified Michael Myers. It’s a haunting chemistry that produced 21’s two most memorable tapes: his 2016 breakout, Savage Mode, and the next year’s Halloween treat with Offset, Without Warning. Now Metro and Savage link again for “Don’t Come Out the House,” the standout cut from the former’s new album Not All Heroes Wear Capes. Through half-whispered verses and spook-filled production, the duo again bring the chills, reanimating the corpses from 21’s past (“All these bodies, I can’t sleep at night, nigga”) and threatening those who oppose him with a similar fate. Here, ASMR sensations heighten acts of violence, sending a tingle down the spine, as the mild euphoria his soft-spoken raps induce matches eerily with the dread in his words.
