As a frequent listener to jazz and hip hop, I have been pushing the boundaries of concert music by incorporating the use of sampling into the genre, while bringing light into unrepresented African history and culture. Recently, I discovered an online library published by the International Library of African Music where there are over 13,000 recordings of traditional African folk songs recorded by composer Hugh Tracey between the 1950s and 1960s. Every single recording is free to download under the creative commons. 
For “Mangondo Postlude,” I sampled a recording from the library featuring two Chewa women singing a heartfelt marriage folk song titled "Mangondo Azipita," over my composition for string trio and piano.
