In addition to the Raschèr Quartet’s numerous solo recitals and collaborations with the world’s leading orchestras, the Quartet has performed with many various instrumental and vocal combinations, including Christain Lindberg, The Kroumata Percussion Ensemble, The London Voices, The West German Radio Choir, The Rias Chamber Choir, The Finnish Radio Choir, The Belgian Radio Choir, The Icelandic National Cathedral Choir, and the Netherlands Chamber Choir. Numerous composers such as Luciano Berio, Erkki-Sven Tüür, Bernd Franke, Stefan Thomas, Giya Kancheli, Maricio Kagel and Sofia Gubaibulina have been inspired to contribute works for the Raschèrs in these combinations.

The Raschèr Quartet is a musical democracy. Therefore, in contrast to many other chamber ensembles, the quartet has no leader.
