Though the fantastical pop star is often considered a musical emissary from another galaxy, Björk is in fact a true citizen of this world. For her sixth studio album, the multifaceted Volta, the 41-year-old traveled from a cabin in Iceland to a boat off Tunisia, then to Manhattan where she lives part-time along with her partner, acclaimed artist Matthew Barney, and their daughter. (Recently, she parked herself in the California desert to headline Coachella.) ''What I like about music [is] that it is abstract,'' she says, seated barefoot and kimonoed in a New York studio. ''You can pass it through to people, situations, whatever you want.'' One such person? Producer Timbaland, who collaborated with Björk on three Volta songs; it turns out the two go way back. ''He sampled one of my tracks 11 years ago. We both love music and beats from the Silk Road North Africa, India.'' But don't expect any bootylicious new videos. ''I didn't approach him because I wanted to be accepted into a new genre. I mean, don't put my music in leather pants and high heels,'' she laughs, ''or I'll hit you!''
