Elmore James (January 27, 1918 -- May 24, 1963) was an American blues guitarist, singer, song writer and band leader. He was known as The King of the Slide Guitar and had a unique guitar style, noted for his use of loud amplification and his stirring voice.
His best known song is the blues standard "Dust My Broom" (also known as "Dust My Blues"). The song gave its name to James's band, The Broomdusters. The song's opening slide guitar riff is one of the best-known sounds in all of blues. It is essentially the same riff that appears in the recording of the same song by Robert Johnson, but James played the riff with electric slide guitar. It was even transformed into a doo-wop chorus on Jesse Stone's "Down in the Alley", recorded by The Clovers and Elvis Presley. Stone transcribed the riff as: "Changety changety changety changety chang chang!"
