The Fiery Angel
Kniplová joined the roster of principal singers at the Mahen Theatre in Brno in 1959, remaining with the company through 1964. During her tenure there the opera company moved to a new building, the Janáček Theatre in 1961. Among the roles she performed there were Emilia Marty in Janáček's "The Makropulos Affair", Judith in Bartók's "Bluebeard's Castle", Katerina in Martinů's "The Greek Passion", Kostelnička Buryjovka in Janáček's "Jenůfa", Renata in Prokofiev's "The Fiery Angel", and the title heroines Libuše and Shostakovich's "Lady Macbeth of the Mtsensk District". During that period, she also appeared as a guest at the Semperoper in Dresden, where she drew particular acclaim for the title role in Verdi's "Aida".
