Day one we got Jack White. Day two we got Soundgarden and now on day three Conan O'Brien has delivered up Fistful Of Mercy featuring Tom Morello on guitar too! Craziness. They play the track which was our first taste from the band back in September titled "Father's Son" taken from their debut, As I Call You Down. Tom adds his trademark sound to the track with a classic Digitech Whammy octave up solo...When you hear it you'll know the ones I mean! Check out the video up top courtesy of The Audio Perv.
