The ensemble was founded in 1985 and is based in Freiburg. The repertoire is focused on the music of the 20th and 21st century while covering the spectrum from classical modernism and the Darmstadt School to contemporary music, but occasionally also includes works composed before 1700, interpreted from a contemporary perspective. The ensemble premiered some 500 works, including compositions by Hèctor Parra, Brice Pauset, Gérard Pesson and Wolfgang Rihm. wikipedia
