1958. In 1960, she toured the USSR, singing concerts in Moscow and Baku. In 1962, she debuted at the Royal Opera House, Covent Garden as Elisabetta di Valois in Don Carlos and Donna Anna in Don Giovanni. Her United States debut had been at the San Francisco Opera in 1956, as Francesca in Zandonai's Francesca da Rimini. She sang in other American opera houses as well, but never at the Metropolitan Opera, despite discussions about her being engaged to sing Tosca there, also in 1956. She sang Chopin's Polish songs in Paris with Nikita Magaloff, a Liszt-Bartók concert at La Scala, and a concert involving 'operas about Turks' in the Venetian carnival at La Fenice, showing her innovative character as an opera singer. Her last appearance on the operatic stage was in 1985, with La Prova di un'opera seria at La Fenice. She continued to appear in concerts until 1992. She was still active as of 2007, and had recently been appointed by La Scala's music director Riccardo Muti to run its school for young artists. Throughout her career, Gencer was particularly well known for her Donizetti, including Belisario, Poliuto, Anna Bolena, Lucrezia Borgia, Maria Stuarda and Caterina Cornaro. Her most acclaimed and best-known performance, though, was the Roberto Devereux she sang in Naples in 1964. Aside from bel canto roles, her repertory included works by such composers as Prokofiev, Mozart and Puccini. She appeared in many rarely performed operas, including Smareglia's La Falena, Rossini's Elisabetta, regina d'Inghilterra, Spontini's Agnese di Hohenstaufen, Pacini's Saffo and Gluck's Alceste. Gencer rose to international stardom in a short time, singing under some of the greatest Italian maestros, such as Vittorio Gui, Tullio Serafin, Gianandrea Gavazzeni, and Riccardo Muti. She contributed to the 'Donizetti Renaissance' with her great performances of Donizetti's forgotten operas. Her repertoire consisted of 72 roles, including operas by Monteverdi, Gluck, Mozart, Cherubini, Spontini, Simon Mayr, Puccini, Prokofiev, Britten, Poulenc, Menotti, and Rocca, encompassing lyric, coloratura, and dramatic soprano roles. Starting in 1982, she dedicated herself to teaching young opera singers. She worked as didactic art director of As.Li.Co. of Milan between 1983–88, and was appointed by Maestro Riccardo Muti to run La Scala's School for Young Artists in 1997-1998. As artistic director of the academy for opera artists in Teatro alla Scala, she specialized in teaching operatic interpretation. In 1996, she appeared in Jan Schmidt-Garre's film Opera Fanatic.
