Nico Fidenco (artistic name Domenico Colarossi; born 24 January 1933 in Rome) is an Italian singer who gained considerable popularity from 1960 onwards, after the release of the song What a sky (Italian: Su nel cielo, taken from the film of Francesco Maselli Silver Spoon Set). Self-taught in music, Fidenco did a few cover versions of film title songs for the Italian market. With the song "Legata a un granello di sabbia", he was the first Italian singer to sell one million copies of a single.
