Best Headliner: Eminem
About halfway through his headlining set, Eminem decided to intensify his recent public flirtation with Nicki Minaj: "I just wanna give a shout-out to wifey," he said, lying down in the center of the stage. "Nicki, let's do this," he said, adding, "She don't even know we go together." This baiting move was a reminder of the feisty hellraiser that Eminem was when he first broke through two decades ago. His Sunday night set highlighted the struggle between that risk-taking genius of the Nineties and the polished pop hitmaker he's become in the last decade. The best moments channeled the former – for an audience teeming with kids born well after he released 1999's Slim Shady LP, the rapper led huge singalongs of classics like "Kill You" and "Stan" for an enthusiastic Sunday night crowd. A special highlight was "The Way I Am," during which Eminem bounced around as a live band with strings elevated the song to new peaks. After that Eminem gave the floor to surprise guest 50 Cent, who flashed his huge grin through a fun throwback set that included his 2003 anthem, "In Da Club." Vocalist Skylar Grey appeared, ethereal as ever, for "Walk on Water" and "Love the Way You Lie," before Eminem segued into some newer tracks. But by then it had started to pour – and those songs felt a little damp too. P.D.
