[source: NME.com] Björk, Sufjan Stevens and Elvis Costello are among artists who offer reflections on Joni Mitchell and the experience of covering her songs on a new website. A Tribute To Joni Mitchell features Björk's comments on the struggles of female artists in a "rock white male world" and Stevens' musings on media mogul David Geffen, as well as thoughts from Annie Lennox and Emmylou Harris. These artists, and others, including Prince, have contributed to A Tribute To Joni Mitchell, due out on Tuesday April 24. The website also features streaming versions of the covers, alongside Mitchell's originals. "As I grow older," Björk remarked in her posting, "I am forced to admit a very, very sad truth (something I promised I would never do): we are living in a rock white male world and because of this Joni is being ignored while someone like Bob Dylan, for instance, has become a saint." Meanwhile, Sufjan Stevens said assembling a cover of "Free Man In Paris" required "more than a few musical somersaults". "Who can possibly surmount Joni's rollercoaster vocal lines with all those odd syntaxes and off-beat pronunciations?"
