The choir was founded in 1981 and has been under the direction of Martin te Laak since 1996. About 30 singers present ambitious choral works of sacred and secular nature of all epochs and styles. The choir is a member of the Association of German Concert Choirs (VDKC) and co-founder of the International Choir Biennale in Aachen.

The Aachener Kammerchor is characterised by a broad repertoire ranging from the Renaissance to the avant-garde, including jazz and pop arrangements as well as folkloristic song settings, with the emphasis on a capella choral music in addition to occasionally instrumentally accompanied works.

The choir has repeatedly participated successfully in competitions and festivals. In 1998 they won first prize at the North Rhine-Westphalia Choir Competition. In 2010 the choir was category winner at the International Robert Schumann Choir Competition in Zwickau. In 2014 they won a first prize at the International Choir Competition for Sacred Music “Laudate Dominum” in Vilnius.

Through numerous concerts at home and abroad (Netherlands, Italy, France, Austria, Hungary, Egypt, Russia, Poland, Czech Republic, Lithuania, Latvia) the choir has made a good name for itself. Its listeners always respond enthusiastically to the very varied repertoire.
