Björk performs 'Cosmogony' on 'The Colbert Report'

Björk and her giant ball-o-yarn hairdo dropped by "The Colbert Report" on Tuesday  night in advance of her month-long New York residency to talk about her groundbreaking app album "Biophilia" and perform her celestial tune "Cosmogony."

In the interview with host Steven Colbert, Björk explained why she'd decided to write an album using a touch-screen format. "I can't really play the guitar and sing at the same time and I couldn't play the piano and sing at the same time, like those troubadour people. So I was like, 'Finally, I can be a troubadour.' "

Though she seemed ready for Colbert's usual onslaught of smarminess, their conversation about the album and its interactive iPad components was for the most part rather informative. Still, he asked whether the touch-screen format, which allows listeners to play along with songs on "Biophilia,"  would allow him to lick the album.

The record is widely considered the world's  first major app album, and in keeping with the theme of the project, a planned three-year tour visits science centers around the world, in addition to traditional venues, with the goal of teaching children about music, science and technology.
