The Rev. Sister Mary M. Nelson, probably a Pentecostal storefront preacher in Memphis, recorded four sides for Vocalion during the late '20s (including one sermon). Unfortunately, little else is known about her life. One of her recordings later appeared on Harry Smith's 1952 folksong compendium Anthology of American Folk Music, and all four of her sides appear on the Document collection Memphis Gospel: Complete Works (1927-1929).
