On August 30th 2006, MIXTUR (MIXTURE) 2003, with a duration of 61 minutes, was premièred during the Salzburg Festival by the Deutsche Symphonie Orchester Berlin.

Following the world première, the superintendant of the Salzburg Festival, Prof. Peter Ruzicka, wrote to Stockhausen:

“I can report of an extremely successful world première of MIXTUR 2003 last night at the Lehrbauhof in Salzburg. The audience was immersed into a new sound world and listened to the Deutsche Symphonie Orchester with great concentration and obvious devotion. The concept of an Electronic Orchestra is truly fascinating!”
