The Delta Blues style comes from a region in the southern part of Mississippi, a place romantically referred to as "the land where the blues were born." In its earliest form, the style became the first African American guitar-dominated music to make it onto phonograph records back in the late 1920s. Although many original Delta Blues performers worked in a string band context for live appearances, very few of them recorded in this manner. Consequently, the recordings from the late 1920s through mid 1930s consist primarily of performers working in a solo, self-accompanied context. Either way, Delta Blues form is dominated by fiery slide guitar and passionate vocalizing, with the deepest of feelings being applied directly to the music.
