In 2006, Placido released, under the name Viola, her first album as a singer, Don't Be Shy..., including 10 tracks (most of which are in English) written by herself, inspired by Stuart Benson. Viola sings in the style of singer-songwriter Suzanne Vega. The second single is "How to Save Your Life". Subsequently, she collaborated with the Italian singer-songwriter Bugo in the remake duet version of his song "Amore mio infinito".
Placido played Nadya in the 2011 film Ghost Rider: Spirit of Vengeance, a sequel to the 2007 film Ghost Rider, both based on the Marvel Comics character of the same name.
