Looks like DMX is back to work just one week after being released from an Arizona prison. The embattled rapper, who's spent more time in and out of jail than on stage or recording in recent years, was filmed working on a new track in Phoenix's Saltmine Studios. From the sound of it, X is in good shape. There's no word on when fans can expect another DMX album, but looks like something's in the works. X recently jumped on the official remix of Busta Rhymes' banger 'Stop the Party,' which also features T.I., Cam'ron and Ghostface.
