How Did Gil Scott-Heron Die?

Gilbert Scott-Heron was an 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".
