Formation.
The Ensemble Sortisatio was founded in 1992 by Matthias Sannemüller in the city of Leipzig. Sannemüller was a pupil from Dietmar Hallmann and member of the Gruppe Neue Musik Hanns Eisler.
The name comes from the Sortisatio concept and refers to the casual combination of the instruments in the ensemble. The idea came from the composer Reiner Bredemeyer.
Members of the quartet are Walter Klingner (oboe and cor anglais), Axel Andrae (bassoon), Matthias Sannemüller (viola) and Thomas Blumenthal (guitar). They are mostly soloists at the MDR Symphony Orchestra in Leipzig.
Sortisatio is today one of the most unusual ensembles in Germany. It inspired many national and international composers to write for them. They have worked with Karl Ottomar Treibmann, Günter Neubert, Thomas Müller, Christian Münch, Thomas Buchholz, Steffen Schleiermacher, Thomas Christoph Heyde, Helmut Oehring, Gerd Domhardt and other German composers.
