[4] Oliveira started her career working as a telephone operator for customs and for the Bank of Angola, but she pursued music on the side.
The following June, she was invited to sing at a private festival of new artists in Azeitão, Portugal, that was attended by various aristocrats.
Produced by the label Valentim de Carvalho, it was the first vinyl record by an Angolan artist, and the first Portuguese-recorded one to be released in Luanda.
[3] In this period, Oliveira stopped playing music and lived in Spain and Switzerland, where she worked as a cook, as a housekeeper, and in child and elder care.
[3][4] Oliveira resumed singing at festivals, bars, and restaurants in her later years, but she could not support herself economically as a musician, relying instead on her pension from the Bank of Angola.
