Jermaine Dupri brought out Jay-Z at So So Def’s 20th Anniversary concert in Atlanta last night, but not everything went as planned – the DJ didn’t have instrumental versions of the songs that Jay was to perform. After the DJ played “PSA” with vocals, Hova cut “N*ggas In Paris” short and said, “Y’all ain’t have to come out here for that. You could’ve just played the shit and put a picture of me up there.” Fair point. Hova then rapped a few bars from “Jigga What” and his verse on “Clique,” a capella style. This is how rap game veterans deal with DJ problems. Watch his performance above.
