"Unfinished Sympathy" was acclaimed by music critics for its distinctive production and Nelson's vocals. It ranked highly on several publications' year-end lists of the best singles of 1991, and has since featured in many polls of the best singles of all time of both music critics and the public worldwide.
Massive Attack at the time was a three-man production team: Robert "3D" Del Naja, Grantley "Daddy G" Marshall and Andrew "Mushroom" Vowles. They used various vocalists on their compositions. Shara Nelson, who also sang on their song "Safe From Harm," appears on this track.
