The underground is a multi-faceted concept in African American culture. Peterson uses Richard Wright, KRS-One, Thelonius Monk, and the tradition of the Underground Railroad to explore the manifestations and the attributes of the underground within the context of a more panoramic picture of African American expressivity within hip-hop.
"The Hip-Hop Underground is an exciting and important read that leaves, as any good text does, readers with many questions and a taste for further review of the pieces of culture that those of us in black communities remember, expunge, and hold forever dear." (Andreana Clay, Journal of American History, Vol. 103, 2016)
