Travis Barker at E3 with Eminem & Rihanna

Eminem performed an electrifying set at Activision's E3 party on Monday night, crushing any doubts that he is truly back in the game after his long hiatus. The Detroit MC headlined a massive bill that included Usher, Will.I.Am, N.E.R.D., Jane's Addiction, Chris Cornell, David Guetta, Deadmau5 and DJ Z-Trip.

Em's set kicked off with his first surprise of the night at the Staples Center, with Travis Barker jumping behind the drums for an acrobatic drum solo. Em joined him moments later (flanked by D12's Denaun Porter), taking the stage just before midnight. He was decked out in a black jacket, black jeans and a silver crucifix hanging around his neck.
