“Wanderlust / Relentlessly craving wanderlust,” Bjork sings on the new Volta (Elektra), and she might as well be describing her aesthetic strategy–few artists seem so devoted to constant change in their musical surroundings. Though longtime associate Mark Bell contributes beats, three tracks were coproduced by Timbaland (including one featuring the Congolese likembe band Konono No. 1) and another incorporates jagged drumming from Lightning Bolt’s Brian Chippendale. Three other pieces are dominated by the kind of stately brass arrangements Bjork used on the soundtrack to Drawing Restraint 9, a film by her husband, Matthew Barney, and she gets simpatico string sounds from Min Xiao-Fen on pipa and Toumani Diabate on kora. It’s tempting to dismiss Bjork’s efforts as forced eclecticism, but her unmistakable style subsumes those of her collaborators and gains new vitality in the process. Her vocals–the fantastical, intuitive melodies, the coy curlicues, the dramatic swooping and soaring–remain both the connective tissue of her work and the seat of its consciousness. Reviews suggest that for this tour she’s recast a few older favorites in dazzling new Volta-esque forms.
