Gil Scott-Heron

American jazz poet, singer, musician, and author known for his work as a spoken-word performer in the 1970s and 1980s. His collaborative efforts with musician Brian Jackson fused jazz, blues, and soul with lyrics relative to social and political issues of the time, delivered in both rapping and melismatic vocal styles. He referred to himself as a "bluesologist", his own term for "a scientist who is concerned with the origin of the blues". His poem "The Revolution Will Not Be Televised", delivered over a jazz-soul beat, is considered a major influence on hip hop music.
