We've shared a few tracks from RZA's film directorial debut The Man With Iron Fists, including a new Wu-Tang track and Kanye's "White Dress". Now we've got another, this time featuring the director himself and the good ole Black Keys. This isn't the first time the pair have worked together, with 2009's rap collab album Blackroc being the first. The video features a battle between RZA and the Keys. The official soundtrack is out tomorrow.
