The BGP's repertoire draws from a sub-genre of bluegrass, the body of music developed in the mountains of the southeastern U.S. during the twentieth century. Bluegrass restyled all types of traditional Appalachian music in the southeast, including the hymns and spirituals of the Christian tradition. However, bluegrass gospel has evolved independently, outside of the church, and is therefore a populist form of spiritual music. The BGP keeps this tradition very much alive as they deliver a gospel meant for all people and all faiths.
