Her compositions were first known only in a small inner circle, but with the Luanda Song Festival, her work became known to a wider public. In the 60s she had formed a duo with the Portuguese journalist Adelino Tavares da Silva, who had just arrived in Angola. They composed four or five songs together and then registered in the Portuguese Writers’ Association, with Adelino as songwriter and Ana Maria as composer. It can be said that the duo revolutionised the Song Festival, when Maria Provocação was performed by Sara Chaves and Mulata é a Noite by Concha de Mascarenhas. They were both accompanied by Ngola Ritmos, the Angolan rhythm group.
