"Biophilia" - and a host of applications representing specific tracks on the album - are out Monday, and are meant to immerse listeners in a complete audio-visual experience.
Speaking to AP ahead of the launch, Bjork said she sees "the structure and shapes of songs" during the creative process.
That led her to work with a team of iPad app designers and musicians. She describes the app technology as "more like an accessory," and says many fans will listen to the album in a traditional way.
The beauty of Bjork's homeland is an inspiration. The singer says the link between the environment and music is "effortless and natural."
