Dr. Dre and Eminem put up a fight on “Die Hard,” their latest collaboration. The adrenaline-fueled anthem, which will appear on Dre’s Detox, premiered during Showtime’s “Fight Camp 360°: Pacquiao vs. Mosley” and features the two rap titans trading bars over a crushing beat.

The West Coast icon acknowledges the pressure he faces from his long-delayed album. “I calculate my next step, which is to accept/ My expectations are sorta too high to meet/ My reputation’s in jep/ Yep, face it/ The fans they been upset yet patient,” raps Dre, while his protégé provides the catchy chorus: “We just keep going ’cause the die hard won’t go down without a fight.”

Did they deliver another knockout? Listen to the television premiere below.
