Biophilia is the seventh studio album by Icelandic singer Björk. It was released on 5 October 2011 by One Little Indian Records and distributed by Nonesuch Records in North America and by Universal Music Group in the rest of the world. Björk composed it as a concept album during the 2008–2011 Icelandic financial crisis, exploring the links between nature, music and technology. Billed as the first "app album", Biophilia is a multimedia project released alongside a series of apps linking the album's themes to musicology concepts. It was followed by a series of educational workshops on four continents.
