Question: Rivers of My Fathers" is a song by a soul and jazz poet whose own term for himself was what?

full_context: Document 1: Gil Scott-Heron: 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.
Document 2: Small Talk at 125th and Lenox: A New Black Poet - Small Talk at 125th and Lenox, also known simply as Small Talk at 125th and Lenox, is the debut album of recording artist Gil Scott-Heron, released in 1970 on Flying Dutchman Records. Recording sessions for the album were originally said to have taken place live at a New York nightclub located on the corner of 125th Street and Lenox Avenue, but liner notes included in the 2012 box set "The Revolution Begins: The Flying Dutchman Masters", Scott-Heron himself insists that a small audience was brought to 'the studio' and seated on 'folding chairs'. By the time of the recordings, Scott-Heron had published a volume of poetry and his first novel, "The Vulture". Well received by music critics who found Scott-Heron's material imaginative, "Small Talk at 125th and Lenox" has been described as "a volcanic upheaval of intellectualism and social critique" by Allmusic editor John Bush.

Document 9: The Mind of Gil Scott-Heron: The Mind of Gil Scott-Heron (subtitled "A Collection of Poetry and Music") is a 1978 album by spoken word and rap pioneer Gil Scott-Heron. Like many of Scott-Heron's albums, the album's content primarily addresses political and social issues; however, "The Mind of Gil Scott-Heron" relies far more on his spoken word delivery than his other albums. Whereas much of the artist's earlier albums contained backup jazz-funk music from Brian Jackson, many of these tracks, which address contemporary issues such as Watergate, the pardon of Richard Nixon and the Attica Prison riot, are either live recordings or studio-recorded songs with little more than sparse drum backing or occasional instrumentation. Many of the tracks featured were included on previous Gil Scott-Heron albums.
Document 10: Soul blues: Soul blues is a style of blues music developed in the late 1960s and early 1970s that combines elements of soul music and urban contemporary music. Singers and musicians who grew up listening to the traditional electric blues of artists such as Muddy Waters, Bo Diddley, Jimmy Reed and Elmore James; soul singers such as Sam Cooke, Ray Charles and Otis Redding; and gospel music wanted to bridge their favorite music together. Bobby Bland was one of the pioneers of this style. This is a subgenre of blues that is very popular with African American audiences but less known by white audiences. The style continues to be popular in the new millennium.
Document 11: Gylan Kain: Gylan Kain is an American poet and playwright. He is a founding member, in 1968, of the Original Last Poets (along with Felipe Luciano and David Nelson). He is known for creating the aggressive, rhythmic delivery of spoken word aka performance poetry as it is known today. He often performs with hand drums or backing musicians such as saxophonists and bass guitarists. His work has often been sampled without pre-consent by well-known artists including Dr. Dre and The Prodigy. One of his performances was sampled into the club hit "Voodoo People" by The Prodigy. Dr. Dre sampled an excerpt of Kain performing his poem, "The Shalimar" on Dre's track entitled "Intro" from the album entitled "The Chronic." After legal action was successfully taken to procure compensation for work sampled by The Prodigy, spokespersons for The Prodigy claimed that efforts had been made to procure permission from Kain for use of his work but those efforts had been unsuccessful because Kain, who values privacy, could not be located in time. Dr. Dre has yet to compensate Kain for work sampled without prior consent. This has led some fans to criticize Dr. Dre as an hypocrite for exploiting the work of an influential Black artist after building a reputation as an empowering force in the black American community as a founding member of N.W.A.
Document 12: Blues People: Blues People: Negro Music in White America is a seminal study of Afro-American music (and culture generally) by Amiri Baraka, who published it as LeRoi Jones in 1963. In "Blues People" Baraka explores the possibility that the history of black Americans can be traced through the evolution of their music. It is considered a classic work on jazz and blues music in American culture. The book documents the effects jazz and blues on American cultural, at musical, economic, and social levels. It chronicles the types of music dating back to the slaves up to the 1960s. "Blues People" argues that "negro music"—as Amiri Baraka calls it—appealed to and influenced new America. According to Baraka, music and melody is not the only way the gap between American culture and African-American culture was bridged. Music also helped spread values and customs through its media exposure. "Blues People" demonstrates the influence of African Americans and their culture on American culture and history. The book examines blues music as performance, as cultural expression, even in the face of its commodification.
Document 13: Bridging the Gap (song): "Bridging the Gap", the second single from Nas' "Street's Disciple", features his father, Olu Dara, and samples music from Muddy Waters' "Mannish Boy" composition. Olu Dara provides the hook of the song by talking about his path and how Nas was born. Nas and Olu Dara performed the song many times before the release of "Street's Disciple", generating buzz as the release of the album drew near. The song is referenced in the title track of The Game's song "The Documentary", when he says, "Now I understand why Nas did a song with his pops".
Document 14: The First Minute of a New Day: The First Minute of a New Day is an album by American jazz vocalist Gil Scott-Heron and keyboardist Brian Jackson, released in January 1975 on Arista Records. Recording sessions for the album took place in the summer of 1974 at D&B Sound in Silver Spring, Maryland.
