In 1967 Rolf Liebermann approached Krzysztof Penderecki with the request to compose an opera for Hamburg. The result was Die Teufel von Loudun, for which the composer himself had written the libretto. The story is based on a true event: in Loudun (France) in 1634, a Prioress of the Ursuline Order accused a priest of diabolical practices for which he was sentenced to be burned at the stake.
The opera had its world premiere on 20 June 1969 and shortly afterwards it was filmed. The leading role of mother Jeanne was performed in a very impressive way by the great Tatiana Troyanos, whose career began in Hamburg. Her portrait of the hunchbacked demonically possessed nun with sexual visions is breathtaking. Everything about her, from head to toe, acts. Her facial expression changes with every phrase she sings and her voice chills you to the bone.
