"Unravel" is the third song on the album Homogenic by Björk, which was released in 1997.
The song features a prominent example of Björk's use of a half-singing, half-speaking technique which, according to folklore specialist Njall Sigurason, is comparable to that of Old Icelandic choir-men.
Structurally, the song is made up of a slowly sweeping melody, strings and distant-sounding electronic beats.
A cover of "Unravel" appears on folk rock artist Okkervil River's split CD Sham Wedding/Hoax Funeral, as well as the Japanese import version of alternative rock band Something Corporate's album North.
The Flaming Lips added the song to their album Late Night Tales: The Flaming Lips, which is a compilation of artists and songs that have affected and influenced the band.
