On this oh-so-cold day, I note that old-school hip-hop literalism may have reached its apotheosis with EPMD‘s “You Gots to Chill,” a 1988 video that featured a leitmotif of actual cold things, just in case all those Yo! MTV Raps viewers thought “chill” was one of those hip-hop slang words that meant something different than its dictionary definition. No, chill meant to chill, and if it took a big bag of industrially produced ice or a giant ozone-sappin’ refrigerator to get the job done for you, than so be it. EPMD performs at Liv on Dec. 11, and it is quite possible that nobody will be chill when that Zapp groove kicks in.
