Video: Eminem x Slaughterhouse Live At G-Shock Anniversary

In what must've been the most widely publicized "secret" event of last night, G-Shock celebrated their 30th anniversary with the help of some serious rhymepower. After Shady Records-signees Slaughterhouse went through their routine at Hammerstein Ballroom, the bossman himself took the stage. Eminem, for whom live performances have become somewhat of a rarity in recent times, threw down some reminders of his status as living legend, whipping out songs like "My Name Is," "The Way I Am" and "Lose Yourself." We've got some footage of both Em's and Slaughterhouse's performances, as well as audio of their interview with Sway on Shade 45.
