In 2008, with the departure of Teresa Salgueiro from Madredeus she joined the popular Portuguese group as part of the newly formed Banda Cósmica, as one of the two vocalists.

The arrangement ended because of financial reasons, caused in part by the decline in sales of compact discs due to the rise in online music sources.

With Madredeus she performed in Portugal, in Germany, in Cape Verde, at the Théâtre de la Ville in Paris, and in the Teatro Calderón in Madrid.

In 2017, she wrote, recorded, and co-produced her first solo EP, together with Jean Massicotte and François Lalonde, who had produced Lhasa de Sela, a singer Damásio very much admired.

[1][3][4] Damásio is a co-founder of AP-IMIDIWAN based in Niamey, Niger, an NGO aimed at sponsoring Nomadic Tuareg children of the desert.
