North

North was used in Gabríela Friðriksdóttir's album Tetralogía.  Björk and dancer Erna Ómarsdóttir contributed to the song. The album was first released as a bonus CD at the 2005 Venezia festival.

Three songs similar to North: Host, Haf and Repose, were used in DR9. An improvised version of it, dubbed Ice Song, appears in the Medúlla dvd. 

North is often referred to as a humming song because in the background there is a loop of Bjork's humming. There is also a crackling/crying sound in the forefront.

The album, Tetralogía, is a musical accompaniment  to a much larger work called Versations/Tetralogia, involving cinema, sculpture, dance, drawings etc. This work examines traditions, myths and origins. Thus, the names of the video components of the work, North, South, East and West, reflect our earthly origin.

Gabríella took a piano melody which she improvised and has been composing since she was a teenager, and asked four musicians – Daníel Ágúst Haraldsson, Björk Guðmundsdóttir, Borgar Þór Magnússon and Jónas Sen – to compose a piece based on the melody. The video and musical works are then edited together to form the Tetralogia, which as a whole forms a quartet, although each video is autonomous. The word, tetralogia, means a series of four related dramas, operas, novels, etc, which fits the composition of this work. 

North: Björk Guðmundsdóttir & Erna Ómarsdóttir
South: Borgar Þór Magnason - upright bass
East: Aurélie Charneux- bass clarinet, (Daníel Ágúst 

        Haraldsson-composer)
West: Jónas Sen - piano 

You may have heard the name Gabríela Friðriksdóttir before. She directed the video for Björk's Where is the Line. There are similarities between this work and a video that was shown in Gabríela's exhibit.

Ink: 

Also known as Ink (The Ice Song). No one knows what Ink  really is. There has been a song found on soulseek with this title. Or, Ink could be a made up name for The Ice Song. Possibly this name came from the working title of Medúlla, which was Ink.
