You know I don't want to get on my soapbox here, but it's interesting to compare Roadrunning with the much vaunted Raising Sand by Plant/Krauss. Roadrunning is a true duets album; Sand features some tracks with either Plant or Krauss singing entirely by themselves (for example Plant sings Fortune Teller; Krauss sings Trampled Rose). Roadrunning may not have won any Grammys but it's perhaps a bit more 'authentic'.
