I think if this CD were free with Uncut Magazine or Mojo it would seem a reasonably interesting set of alternative cover versions. Interesting, as in one play, then slot away with the other free CDs. In all honesty, it's not very good though.
The original songs are excellent, of course, the artists singing the songs are also very good, but the combination didn't work for me. I'm a massive fan of Lucinda Williams, but this is rather a dreary version of Positively 4th Street. God help me, but I actually prefer Mick Hucknall's version! Rickie Lee Jones is always hit and miss when it comes to covers. A miss for me. Shelby Lynne does a low key version of Don't Think Twice (in style of her Dusty covers LP). It's quite nice, but a bit underwhelming. Good Cowboy Junkies version of Once I was, though.
Definitely an LP to listen to on spotify, then download a few tracks, but on the whole uninspiring.
