 Nowadays the Vienna Mozart-Trio is one of a small group of ensembles known in virtually all the important music centres.

Irina, Daniel and Diethard Auner are not bound by any contracts with orchestras. Their artistic independence enables them to achieve a musically free and unconventional interpretation of utmost intensity.

The musicians consider it as their vocation to convey music as a spontaneous and original experience. As a result, they have made a wide audience familiar with all epochs and styles and all the possibilities of musical expression, ranging from the great Viennese classics - with W.A. Mozart as one of the earliest composers of the musical genre of the piano trio - to the present day.

Since 2012, the Vienna Mozart Trio has been organizing and directing its own international music festival at Schloss Hunyadi on the southern city limit of Vienna. Renowned musicians and ensem­bles make guest appearances there each year: the Sommerkonzerte Wienerwald.

Since July 2017, Daniel Auner has been playing a violin from Giovanni Battista Guadagnini named “Elia” which the Österreichische Nationalbank presented to him as a special award.
