Bjork has worked with a typically eclectic crew of collaborators on her next album, due in late spring via Atlantic. According to a post on the artist's Web site, the as-yet-untitled album features two tracks produced by Timbaland and another two featuring vocals by Antony Hegarty of Antony and the Johnsons.

Additional guest appearances have been turned in by Toumani Diabate on kora, Konono No. 1 on electric thumb piano and drumming from Lightning Bolt's Brian Chippendale. "This record is a Bjork production par excellence," the site says. "No stone left unturned to seek out the perfect pitch."

The new album is Bjork's first since 2004's stark "Medulla," which boasted contributions from Mike Patton, Rahzel, Matmos and Robert Wyatt.

Bjork's site also confirms the Icelandic singer will return to the road this year. Billboard.com understands she may appear at a major U.S. festival in the coming months.
