The album, Amețiți de fum, contained 10 songs composed by her father and dances orchestrated by Cătălin Tîrcolea.

Although member Gigi Antonescu was reluctant to join at first,[5][6] Andrè proved to be a national success, gaining notoriety both within Romania and internationally, with their target audience being teenagers.

The album included the song "Un univers mai liniștit," known in other countries as "Iluzii", which was previously performed by Bălan at Eurovision.

The group released a duo album, O noapte și-o zi, in 2001 as well as a single of the same name accompanied by a video, but split again.

[25] Between the two seasons, she was selected to participate in the PRO TV international version of Dansez pentru tine, titled Dancing Around the World.

[27] The pair ultimately ranked in second place,[28] enjoying great popularity among the Mexican public,[29][30] and received a contract from EMI Music to record an album.

[47] In 2015 the artist was chosen by Disney to provide the Romanian singing voice of Esmeralda for the feature film The Hunchback of Notre Dame.

[49] Her album Superwoman visibly distanced its musical style from her past recordings, and contains elements of samba, rock and roll, and jive,[49] and finalizing her image as a soloist dancer.
