The nickname was used before in her brothers' musical group the "Trio Tariácuri" and in her own duo with her sister, "Las Tariácuritas". Mendoza was also an accomplished actress of film, television, and radio; she participated in several films during the 1950s and 1960s.

Through the majority of her career she was accompanied by El Mariachi Vargas de Tecalitlán, and recorded numerous rancheras and boleros by José Alfredo Jiménez, Cuco Sánchez, José Ángel Espinosa, Gabriel Ruíz and Tomás Méndez.
