Tuesday night's sold-out Jay-Z concert at Madison Square Garden catered to recently-converted fans ("Empire State of Mind" was played in the middle of the set) and longtime diehards (the closing encore was packed with bounce-inducing early hits like 1999's "Big Pimpin" and 1998's "Hard Knock Life" and "Can I Get A...").

A surprise guest nearly stole the spotlight from Hova, though. Jay-Z took an unexpected break in the middle of the set, ceding the stage to Young Jeezy, who asked the crowd to pray for prison-bound Lil Wayne. As Nicki Minaj and Jeezy performed Young Money's "Bedrock," Lil Wayne bounced into view unannounced, ricocheting off the stage like a teenage cat. The crowd squealed a collective "OMG!" like tweens at a Justin Bieber concert. Rapper Drake completed the entourage as they segued into the now-apropos mixtape jam "I'm Going In." Each of Lil Wayne's going innnn's was savored by the crowd, as it was likely to be the last performance before the rapper starts a one-year sentence for gun possession.
