DJ AM is getting back behind the turntables for the first time since surviving a flaming plane crash that left him critically injured last month. AM will serve as Jay-Z’s spin doctor as the platinum-selling rapper kicks off his multi-state tour at the Palladium Nightclub in Hollywood on Wednesday night.

“He’s the greatest rapper in the world,” the 35-year-old jock told PEOPLE Tuesday. “This is the biggest thing that’s happened in my career.”
