The Stadler Quartet has worked with numerous composers including George Crumb, Henri Dutilleux, Helmut Lachenmann (CD and DVD), Geörgy Kurtág, Wolfgang Rihm, Jörg Widmann, Friedrich Cerha (CDs), Georg Friedrich Haas, Steve Reich, Thomas Larcher, Chaya Czernovin, Johannes Kalitzke (CD), Luca Francesconi, Huang Ruo and Giya Kancheli. They have performed several times at the Salzburg Festival and play regularly for the Mozarteum Stiftung. They have given concerts in Milan and Rome, and have toured to Germany, Hungary, Albania and Spain.
The current players - Frank Stadler, Izso Bajusz, Predrag Katanic and Florian Simma - also work in leading positions in top Austrian orchestras (the Mozarteumorchester Salzburg and Camerata Salzburg). Since 2017, the Stadler Quartet has focussed on the works of Mieczysław Weinberg. In 2019, they organised and performed a Weinberg Festival in Salzburg, which marked the 100th birthday of the composer. They were joined by the distinguished artists Gidon Kremer and Mirga Gražinytė. The Festival was successfully repeated in December 2020 and streamed worldwide on the internet platform "IDAGIO". The third Weinberg Festival will be held in December 2021.
