The song features a prominent example of Björk's use of a half-singing, half-speaking technique which, according to folklorist Njáll Sigurðsson, is comparable to that of Old Icelandic choirmen.
[1] Structurally, the song is made up of a slowly sweeping melody, saxophones, a church organ, and distant-sounding electronic beats.
Even though "Unravel" was not released as a single, a music video was made by Lynn Fox to promote Björk's Greatest Hits tour.
The video itself depicts Björk in a deep sea-like environment, wearing a billowing dress as a large and furry unidentified sea creature grows out of her back in a strings-like manner.
[7] English songwriters Wayne Hussey and Julianne Regan featured a cover of the song on their collaborative album Curios.
