In their previous visit (January 11, 2011), band members Dan Auerbach and Patrick Carney were pitted against Vampire Weekend's Ezra Koenig in "Sell Out Off," in which the victor, to be determined by the number of commercials their songs appeared in, was to receive Colbert's Grammy vote for Best Alternative Music Album. Despite an inconclusive result, The Black Keys, nonetheless, went on to win three Grammys the following month.
