The Klangforum Wien is an Austrian chamber orchestra, based in Vienna at the Konzerthaus, which specialises in contemporary classical music.
Principal guest conductor is Bas Wiegers [nl] since the 2018/2019 concert season.
The group is often cited as Austria's leading contemporary music ensemble,[4] and is particularly noted for its performances of music by composers of the German-speaking countries, including Helmut Lachenmann, Wolfgang Rihm, and Hans Zender.
Klangforum Wien has been in residence at multiple music festivals, including the Donaueschingen Musiktage, Wiener Festwochen and Wittener Tage für neue Kammermusik.
[6] Klangforum Wien participated in the work-in-progress Infinite Screen by artists duo Arotin And Serghei, with creations at Wiener Konzerthaus (2013 and 2021), at La Biennale di Venezia (2015), and at Centre Pompidou (2021).
