After-W.D.-Stewart-and-Walter-Jackson
After W.D. Stewart and Walter Jackson is a generative electronic music composition, implemented as a computer program in the SuperCollider programming language and sound synthesis environment. The program autonomously generates and resynthesizes permutations, transformations, and juxtapositions of musical material drawn from a parametric transcription of two recorded musical performances, W. D. Stewart’s Levee Camp Holler, and Walter Jackson’s Tangle Eye Blues. The two performances were recorded in 1947 by folklorist Alan Lomax, at Mississippi State Penitentiary (also known as Parchman Farm) when Stewart and Jackson were imprisoned there. Both performances were examples of a song style known as a field holler, which was sung by African Americans throughout the American South, and especially in the Mississippi Delta, until around the middle of the 20th century.
