[citation needed] Vidal was a founding member of the New York City-based band Desmond Child & Rouge.

Vidal, as a member of Rouge along with Diana Grasselli and Myriam Valle, was asked by Paul Shaffer (the band's keyboardist), to sing on a live comedy album that he was the musical director on for Gilda Radner.

They toured Boston and Chicago, where the performances were made into the film Gilda Live directed by Mike Nichols.

When the band parted ways, her first solo endeavor was an album with EMI, where she worked with producer John "Jellybean" Benitez.

While working on the album, she was asked to sing the theme song for the 1984 film Body Rock, produced by Phil Ramone.

Jimmy Iovine then signed Vidal as a solo artist to A&M Records after hearing her demo of "Do Me Right", which had been written and produced for her by Desmond.

Vidal contributed backup vocals to Kiss's Paul Stanley's solo album, Stevie Nicks' single "I Can't Wait" as well as a few other tracks from Nicks' solo album "Rock a Little", and was a featured vocalist for The Smithereens' single "A Girl Like You".

Other highlights include vocals for artists such as: Aerosmith, Seal, Celine Dion, Toto, Bette Midler and Cher.

Vidal has written songs with Desmond Child, Billy Steinberg, and Rick Nowels, including Ace of Base single "Every Time it Rains" and Belinda Carlisle's "California."
