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. Four singles were issued before the album's release in 2011. "Crystalline", co-produced with English dubstep duo 16bit, was released as the lead single on 28 June 2011, accompanied by a music video directed by longtime collaborator Michel Gondry. It was followed by the singles "Cosmogony", "Virus" and "Moon". Björk promoted the album with the Biophilia tour, which began at the Manchester International Festival in June 2011 and ended in September 2013. Another track related to the project, "Náttúra", was released as a single in 2008.
