Stamps Quartet

John Daniel Sumner (November 19, 1924 – November 16, 1998) was an American gospel singer, songwriter, and music promoter noted for his bass voice, and his innovation in the Christian and Gospel music fields. Sumner sang in five quartets and was a member of the Blackwood Brothers during their 1950s heyday. Aside from his incredibly low bass voice, Sumner's business acumen helped promote Southern Gospel and move it into the mainstream of American culture and music during the 1950s and 1960s.
