Sammy Salvo was an American pop singer known primarily for his work in the late 1950s and early 1960s. His music is characterized by a blend of pop and rockabilly, with a distinct Southern influence reflective of his Alabama roots. Salvo's most notable song, "A Mushroom Cloud," released in 1961, was one of the first popular songs to address the fear of nuclear war. While not widely recognized in the broader music history, Salvo is considered a significant figure in the early evolution of American pop and rock-n-roll.
