Ral Donner was an American early rock and roll musician known for his striking vocal similarity to Elvis Presley. His most successful song, "You Don't Know What You've Got (Until You Lose It)", reached number four on the Billboard Hot 100 in 1961. Donner's music, characterized by a combination of rock and roll, pop, and soul, was significantly influenced by Presley and his style, making him a key figure in the continuation of the rockabilly genre. Despite his short career, cut short by his untimely death in 1984, Donner's Elvis-like sound played a role in sustaining the rock and roll tradition of the late 1950s and early 1960s.
