Elektra has pushed the release date of Bjork's "Greatest Hits" album from Sept. 3 to Oct. 8. As previously reported, the song list for the 15-track set was chosen via fan voting on Bjork's official Web site. "Greatest Hits" embodies "the story of how I got to where I am today and in my musical words to say how I developed as a musician," Bjork said in a statement.

The same day, Elektra will unveil a six-CD box set, "Family Tree." According to Bjork's Web site, "the production of the 'Family Tree' package is quite unique and has proven to be more time consuming than first anticipated, with it being rather more like a folder than a box, containing one standard CD, four mini-CDs, and booklets."

Although the tracklist has not yet been revealed, "Family Tree" will include one disc featuring 12 of Bjork's own hand-picked favorites. Two "Roots" discs will comprise 10 tracks from early in the artist's career, including material from her former band the Sugarcubes and a flute piece she penned at age 15. The four-track "Beats" CD features Bjork's first forays into unconventional rhythms following her exit from the Sugarcubes, with assistance from producers Graham Massey and Mark Bell.

The final two discs are filled with orchestral interpretations of Bjork songs by the Brodsky Quartet, with whom she collaborated in 2000 for several concerts in London.

In addition, a long-awaited DVD of Bjork's December 2001 performance at London's Royal Opera House will also arrive on Oct. 8. A clip of the track "Unison" is available on the artist's Web site.
