The project was produced by Jack Wright and is a benefit for the Lonesome Pine Office on Youth in Wise County, Virginia.
The songs included cover a range of topics related to coal culture such as mining accidents and black lung disease.
Some of the artists are natives of the U.S. coal mining region while others have less direct ties.
Both vintage recordings and contemporary music have been combined with detailed liner notes giving context to both the songs and the artists.
Musicologist Archie Green adds a "Sanctus" note to Wright's "Introduction."
