Nico Fidenco, artistic name of Domenico Colarossi, (Rome, January 24, 1933), is an Italian singer who gained considerable popularity from 1960 onwards, after the release of the film What a sky, (Italian: Su nel cielo, taken from the film of Francesco Maselli I delfini).
Self-taught in music, Fidenco did a few cover versions of film title songs for the Italian market. This interest in cinema lead him to be a prolific soundtrack composer.
