Bjork Album, Tour Delayed

Icelandic singer/producer's Vespertine now slotted for August release.

The release of Björk's next album, Vespertine, has been delayed from its original date of May 22 to sometime in August, according to a spokesperson for her label.

The Icelandic singer/producer has also postponed the launch of her tour in support of the album. The San Francisco experimental-electronic duo Matmos, who supplied one of several remixes for the release of Björk's 1998 single "Alarm Call," will still open for Björk on the tour and perform as part of her band. New York harpist Zena Parkins will also appear on the tour dates.

No official reason was given for the delay of Vespertine, which will be Björk's fourth full studio album and her first since 1997's Homogenic. Her most recent release was Selmasongs, the seven-song soundtrack to last year's "Dancer in the Dark," in which she starred (and earned a Golden Globe nomination for Best Actress).

Björk will perform the EP's Oscar-nominated song, "I've Seen It All" (RealAudio excerpt), at the March 25 Academy Awards ceremony in Los Angeles accompanied by the 55-piece house orchestra.
