Gospel blues

Gospel blues (or holy blues) is a form of blues-based gospel music that has been around since the inception of blues music. It combines evangelistic lyrics with blues instrumentation, often blues guitar accompaniment. According to musician and historian Stefan Grossman, "holy blues" was coined to originally describe Reverend Gary Davis's style of traditional blues playing with lyrics conveying a religious message. Davis and Blind Willie Johnson are considered the genre's two dominant performers, according to Dick Weissman.
