The Jordanaires were a well-known American vocal quartet that played a significant role in the development of rock and roll, gospel, and country music. They gained fame as the background vocal group for Elvis Presley from 1956 until 1972. The group's harmonious blend of voices became a signature sound in many of Elvis's hits, including "Can't Help Falling in Love" and "It's Now or Never". The Jordanaires' influence extends beyond Presley, as they have recorded with numerous other artists, contributing to the rich tapestry of American popular music.
