“Heathens,” Twenty One Pilots’ contribution to the Suicide Squad soundtrack, has been pretty much inescapable on pop radio for the past few months. Among the many who have appreciated it — or been subjected to it, depending on whom you ask — is Vic Mensa, who’s just released a new freestyle over the song’s menacing beat. Mensa takes things from pretend-scary to real-life scary, talking about the very real violence he’s encountered on Chicago’s South Side (and making a Twenty One Pilots joke while he’s at it). Listen and appreciate Mensa’s Joker-aping cover art below.
