[3][4][5] After the end of World War II, she left Belgium to return to her birth country,[3] travelling concealed on a freight train with the help of an American soldier.
[9] She also appeared as Marcellina in Mozart's Le nozze di Figaro, Preciosilla in Verdi's La forza del destino, Brangäne in Wagner's Tristan und Isolde and Herodias in Salome by Richard Strauss.
[10] Cvejić made her house debut at the Metropolitan Opera on 14 April 1961, again as Amneris in Verdi's Aida, alongside Birgit Nilsson in the title role.
[11] A reviewer noted in the New York Herald Tribune that she "was duly regal as well as attractive in appearance, and her voice gave an impression both of generous volume and appropriate warmth, while both in song and demeanor she realized the expressive resources and range of her role".
[13] In 1964, she appeared as Eboli in Don Carlo, with Tucker in the title role, and Giorgio Tozzi as Philipp II of Spain,[14] and the same year as Azucena in Il trovatore, conducted by Thomas Schippers.
[3][5][20] Cvejić had a dark-timbred, beautifully formed contralto voice,[3] which Roksanda Pejović describes in her entry in Grove's as "even, polished, technically assured".
