After the tsunami that struck Southeast Asia in late 2004, Björk began work on a new project titled "" to help raise money for a relief fund. This project recruited fans and musicians from around the world to either cover or remix the 1995 track "Army of Me." From over 600 responses, Björk and her co-writer Graham Massey picked the best 20 versions to appear on the album. The album was released in April in the UK and in late May 2005 in the US. By January 2006, the album had raised about £250,000 to help UNICEF's work in the southeast Asian region. Björk visited Banda Aceh in February 2006 to view some of UNICEF's work with the children who were affected by the tsunami.
