Olivia Merilahti and Dan Levy met in 2005 while recording the music for the French film Empire of the Wolves directed by Chris Nahon and produced by Gaumont.

The band's name is derived from the first note of the solfège scale, and is pronounced as the English word "dough", with a long "o" sound.

This included "The Bridge Is Broken", composed for a contemporary dance ballet titled Scène d'amour by Finnish choreographer Juha-Pekka Marsalo.

They scored the dance works Prologue, Perle and Cinderella by Juha-Pekka Marsalo, as well as poetry lectures by Carolyn Carlson) and the stage play Laure by Colette Peignot.

It was acclaimed as an eclectic record, drawing inspiration from various genres as pop, folk, rock and hip hop, while maintaining integrity and an original approach.

This was followed up in July with the announcement of the band's third album Shake Shook Shaken, released on 29 September in France, Benelux, Switzerland and Andorra.

18 August saw the release of the third single from the album "Despair, Hangover & Ecstasy", which was followed up with a music video on 21 October premiered online by The Fader.
