It would be hopelessly naive to suggest that singers work better for a taste of pain. And yet…K.T. Tunstall, having had her marriage break up and her father die, has produced an album way ahead of anything she’s done before. And the Civil Wars, having done one very good album, have now produced a second (and presumably last) which features beautiful harmonies, despite the fact that the two performers were barely speaking. The lyrics are almost too tough to take (shades of Rumours, or Shoot Out the Lights) but there’s a horrible, irresistible thrill about the power of what’s going on.
