Title: Gil Scott-Heron
Passage: Gilbert "Gil" Scott-Heron (April 1, 1949 – May 27, 2011) was an American soul and jazz poet, musician, and author, known primarily for his work as a spoken-word performer in the 1970s and 1980s.  His collaborative efforts with musician Brian Jackson featured a musical fusion of jazz, blues, and soul, as well as lyrical content concerning social and political issues of the time, delivered in both rapping and melismatic vocal styles by Scott-Heron.  His own term for himself was "bluesologist", which he defined as "a scientist who is concerned with the origin of the blues".  His music, most notably on "Pieces of a Man" and "Winter in America" in the early 1970s, influenced and helped engender later African-American music genres such as hip hop and neo soul.  In fact, Scott-Heron himself is considered by many to be the first rapper/MC ever, a recognition also shared by fellow American MC Coke La Rock.
