As a Joni fan for 25+ years I was intrigued by this album with all its big name stars covering my favourite songs. Unfortunately the excitement barely survived the first few tracks in which it became clear that the style, vocal tone and music of these "tributes" is a very poor substitute for Joni's mellifluous dulcet tones and stylish music.
The tracks that stay close to the original style are marginally better than the more "experimental" efforts, but on the whole they all range from awful to atrocious. There are no tracks that I could honestly call a good cover version - but this was a Tribute album, so perhaps that wasn't the intention and fans of Bjork and Prince etc. will be delighted with their artistic tratment of Joni's songs. Personally I'll stick with the originals, thank you.
