Casey Bill Weldon (July 10, 1909–196?) was an African-American blues musician born in Pine Bluff, Arkansas who later lived and worked in Chicago, known as one of the great early pioneers of the slide guitar.He played upbeat, almost hokum, tunes, usually in a band. He is also known as a member of the Memphis Jug Band, with whom he played and recorded. Among the premier “Hawaiian-style” blues guitarists, “Casey Bill” Weldon’s voicings, fluidity and tunings were creative and imaginative, as were his arrangements. He was married to Memphis Minnie in the ’20s with the two making influential recordings together in the late ’20s. Weldon played in medicine shows before beginning his recording career in 1927 for Victor.
