Nico Fidenco was born on January 24, 1933 in Rome, Lazio, Italy as Domenico Colarossi.
As a singer he enjoyed great popularity since 1960, the year he recorded "What a sky" ("Su Nel Cielo" , from Francesco Maselli's I Delfini) . Fidenco was already working as pianist and arranger at Italian RCA in Rome, where he was introduced by Franco Migliacci. His songs were performed by RCA artists.
At that time, features by some deemed as faults fascinated artistic director Enzo Micocci who said thise faults highlighted the personality of the singer. Thi made Micocci interested in Fidenco, as he did for the same reason spark his interest in Gianni Meccia the first Modugno ( both discovered by him). Francesco Maselli wished to include a Paul Anka song in the soundtrack of the aforementioned film I Delfini (The Dolphins) but te amount of money requested for the royalties was deemed excessive. Maselli then turned to Micocci , who offered him a new song composed by maestro Giovanni Fusco . The demo was recorded by a young Tony Little , the son of Fusco and Fidenco . The latter was the one preferred and picked by the production. The record company initiallyhad not planned to do a 45rpm of the song, however the pressures of both retailers and wholesalers, due to customer requests (the film was not a success , but the song enjoyed an unexpected word of mouth ), pushed the ' label not only to publish the English version, but to quickly bring back Fidenco to the studio to record on the Italian version of the song on same orchestral tracks and use it as the B side of the 7inch. After "What a sky" Fidenco recorded other hits such as "The World of Suzie Wong" (1961), and the Italian version of the theme song of the same film, "Con Te sulla Spiaggia" and "Se mi perderai" (1965), but especially "Legata a un granello di sabbia" (1961) the first 45rpm in Italy to sell over one million copies, all recorded for Italian RCA. His only took part in the Sanremo Festival in the unfortunate edition of 1967 that went down in history for Luigi Tenco 's suicide. Fidenco, who was presenting a song by Gianni Meccia "Ma piano (per non svegliarti)" together with the American singer Cher, failed to bring the song to the final of the competition. The reason of the elimination according to the singer was Cher's unpreparedness , who arrived only the day before the competition, not knowing the song (and not knowing Italian), and forced to learn the lyrics phonetically without understanding the meaning, assisted by her then husband Sonny Bono, musician of Italian origin.
After having cut down on recording songs, Fidenco began to deal again with film-scores, composing for genre films ranging from spaghetti westerns (the first was ALL OMBRA DI UNA COLT) to erotic films such as LA STRANA LEGGE DEL DR. MEGA(1972), LA RAGAZZINA (1975) IMMAGINI DI UN CONVENTO (1979) and the Black Emanuelle series, to cartoon songs for "Hela Supergirl", "Don Chuck Castoro", "Cyborg", "I Nove Supermagnifici". "Sam Il Ragazzo Del West", "Bem Il Mostro Umano" and TV shows such "Harlem contro Manhattan" (from 1978 Diff'rent Strokes), and later the music of "Zombie Holocaust" (1980) and Porno Holocaust by Joe D' Amato.
From 1984 to 1994 he teamed again with colleagues Riccardo Del Turco , Jimmy Fontana and Gianni Meccia forming Super 4, a quartet mainly specializing in remakes of famous songs from their repertoire of the '60s and in 1985 by publishing an album for Italian RCA and getting discreet commercial sucess for it.
