The Kammeroper in Vienna has been firmly established as part of the city's cultural life for nearly sixty years and aims to retain the spirit and character that its founder, Hans Gabor, wanted it to have.

When the Austrian government stopped subsidising the theatre in 2011, a new concept for productions was developed in cooperation with the association responsible for the Wiener Kammeroper and with the agreement of the City of Vienna. The Vereinigte Bühnen Wien show their commitment to this concept by placing their expertise and their organisational and financial resources at its disposal by exploiting synergies.

Since the 2012/13 season, the Theater an der Wien has been responsible for the Kammeroper programme and presents opera productions and portrait concerts. The broad spectrum of the intimate chamber opera repertoire complements the Theater an der Wien's programme and also picks up on some of the dramatic focal points of the operas presented there.

The foundation of the Junges Ensemble of the Theater an der Wien (JET) consisting of six young professionals breathes new life into the historic venue on Fleischmarkt. The rising singers were selected from numerous applicants and, following a period of intensive training and experience in international opera studios and ensembles, have already proved their qualities.

Currently, the second generation of the JET can be seen and heard performing lead roles in productions at the Kammeroper and in smaller roles at the Theater an der Wien itself.
