J.D Sumner, Ed Enoch, Ed Hill and Rick Strickland make up the amazing J.D Sumner And The Stamps Quartet. The lowest vocal bass note ever recorded by the Guinness Book of World Records came from J.D. Sumner. It's only one of a long list of great moments in the life of the late musical legend. For much of his career he headed up the Stamps Quartet, one of the greatest success stories in the gospel music industry.
