For several years, the iconic Mark Knopfler and Emmylou Harris have been quietly recording a remarkable collection of duets whenever the Grammy winning artists could steal away from their own illustrious careers. The extraordinary result is All the Roadrunning. The songs from their Nashville sessions, all originals, while undeniably modern, have the appeal of classics, whether country, Celtic flavored or gently soulful. All the Roadrunning is Knopfler & Harris making music and, as they lyric for "This is Us" puts it, making history.
