Björk’s new album Biophilia was composed partly on her iPad.

In collaboration with Apple, it will be the “first app album”, a multi-media extravaganza with each song corresponding to an individual app.

Discussing the Biophilia project on her website, Björk tells us that she researched “where music and nature meet, and structures in nature and structures in music and where they are similar and then going and writing the songs.”

“Crystalline” is our first taste of the music.
