Fatback was basically a funk band that recorded in the 1970′s and 80′s.
As far as this site is concerned, however, it is one track in particular that lands it a place on this site.
The track is called “King Tim III (Personality Jock)”. It was released in 1979 and is considered by many to be the first hip hop song in history.
The song was released just before a certain other tune called “Rapper’s Delight“.
It appears on their 1979 album “XII”.
