It’s been a minute since we’ve heard from them, but the much-heralded duo of Pacewon and Mr. Green are back at it with “Massacre,” a bruising new single featuring Bronx spitter Chris Rivers (Big Pun’s son). Pacewon leads the charge over the slapping production from Mr. Green, who blends and manipulates layers of samples on top of one another. It’s a fitting setting for his tag-team partner, who raps about choking trash rappers and hanging them from his rear-view. The same goes for Rivers, who bodies the beat with references to Super Smash Bros. and King Arthur in addition to a variety of flows. “Massacre” is now available through the digital outlet of your choice via Raw Poetix Records.
