This is Björk's first solo single to be released entirely in Icelandic.
Coolplanet2009 has joined forces with numerous so-called Cool Friends and Partners, such as Yann Arthus-Bertrand and Good Planet, the Icelandic rock band Sigur Rós, Björk’s NGO Náttúra and the three chairwomen of the Road to Copenhagen: Margot Wallström, Vice President of the European Commission, Gro Harlem Brundtland, UN Special Envoy on Climate Change and Mary Robinson, former President of Ireland.
