Puceanu started to sing professionally when she was 14, with the "Brothers Gore taraf", one of the most famous tarafuri of the time.
She was highly appreciated for her unique voice and for the sensibility of her singing.
Despite her professional success, she had an unhappy love life, which led to some drinking problems, and also affected her voice in the latter part of her life.
She was married to the accordionist Bebe Șerban (also known as "Bebe de la Petrichioaia" – "Bebe from Petrichioaia"). Cornelia Teișanu, her niece, is also a singer.
Puceanu died as a result of a car accident in 1996.
