This duo was formed by Teca Calazans and Ricardo Vilas in France, where they lived from 1969 to 1979; they recorded seven albums. Active from 1971 to 1981, the duo performed in several European countries, divulging Brazilian popular and folkloric musics. Jardin Exotique (1979) included Cartola's "Tive Sim" with the participation of the composer. In the same year, they returned to Brazil where they still recorded two albums.
Their most important songs were "Caicó" (Villa-Lobos/Calazans/Milton Nascimento), "Estrela da Canção" (Villas), "Coco Verde" (Calazans/Villas), "Aguaceiro" (Calazans/Villas), and "Povo Daqui" (Calazans).
