[1][non-primary source needed] Rettore started her singing career in 1973.

Her most popular hits are Splendido Splendente (Splendid Shining), Kobra, Donatella, Lamette (Razor Blades), This Time, Io Ho Te (I've Got You), Amore Stella (Love Star) e Di Notte Specialmente (Especially By Night).

The majority of Rettore's albums are a mixture of pop, rock, disco music and ska.

In the mid-1980s she experienced a slow decline in popularity, and she had to wait almost a decade before recording a top 10 Italian charts hit.

Rettore's most recent album, Stralunata, is an anthological double CD & DVD which entered directly to n. 2 and stayed in the top 10 Italian charts for two months.
