Roots of Rosco Gordon

John Marshall Alexander Jr., known by the stage name Johnny Ace, was an American rhythm-and-blues singer. He had a string of hit singles in the mid-1950s. He emerged as a prominent figure in postwar R&B and gained fame with hits such as "My Song", "Cross My Heart", and "Pledging My Love". Ace's smooth vocal style and romantic ballads made him a popular artist, particularly on R&B radio stations and jukeboxes. At the height of his career, he toured extensively and was regarded as one of the most promising young stars in the genre.

Riley B. King, known professionally as B. B. King, was an American blues guitarist, singer, songwriter, and record producer. He introduced a sophisticated style of soloing based on fluid string bending, shimmering vibrato, and staccato picking that influenced many later electric guitar blues players. AllMusic recognized King as "the single most important electric guitarist of the last half of the 20th century".
