Born in London to Jamaican parents, Shirley has lived in Australia for many years. Her way to become the lead vocalist for the Silverbacks was pure coincidence. At a concert by Sharon Jones & The Dap-Kings in Madrid, the Tuxcone Records team was also attending, Shirley was brought on stage by the audience. She sang with Sharon, and Tuxcone knew immediately that they had to sign Shirley. She accepted on the spot. The rest is history.
The Silverbacks are the stars of the Spanish soul scene and the flagship band of Tuxcone Records, on whose sound the label is built.

In March 2016 Shirley started leading the Silverbacks, entering the international soul scene with their debut album "Black Rose". This award-winning album did not only inspire the critics worldwide, but also colleagues such as Lee Fields. "Black Rose" - pure soul with a touch Afrobeat - earned Shirley Davis & The Silverbacks the title "Best New International Artist" at the Pop-Eye Awards in 2016.

In April 2018 Shirley & the Silverbacks released their 2nd album "Wishes & Wants" on which the melodies and rhythms sound stronger than ever before - a colourful blend of exotic soul and funk; light and heavy.
