Costa went back and forth between Los Angeles and Europe, maintaining a sharp childhood sense while molding a sophisticated music career. By age seven, she sang "On My Own" with the Don Costa Orchestra in Milan. From there, her sassy persona was captured on record. She released several albums throughout Europe, Israel, Central and South America, most of them going platinum. Whirlwind success, however, was not overwhelming. Costa's early days spent in her father's recording studio, meeting Quincy Jones, Sly Stone, and Sammy Davis Jr., perfected this inspiring singer/songwriter into the humble individual she's turned out to be.

Her late teens were spent on the top of the German charts and by the time she reached her mid-twenties, she called Australia home. She became a favorite among the Outback, landing a deal with Mushroom Records and issuing Butterfly Rocket in the mid-'90s. It garnered a nomination for "Best New Artist" at the annual Australian Recording Industry Awards.
