She used brass instrumentation for almost every song on the album, and most of the instrumentation is courtesy of an all-female Icelandic brass ensemble. However, Björk also used samples from her previous project, "The Music From Drawing Restraint 9", as in the case of "Vertebræ by Vertebræ" and "Declare Independence", because she was interested to find out how the sounds from that soundtrack album would sound in a less ambient or atmospheric soundscape. For the song "Pneumonia", also featuring an independent horn section, she drew inspiration from her own bout with the disease, and an emotionally moving viewing of the film "Pan's Labyrinth".
