You should have stepped over to the TU Berlin. A few month's before that concert, there was a performance/recreation of a concert that took place in Koln cathedral of various Messiaen organ works, played back on the WFS system installed at the TU. Much, much bigger than Henke's setup at Tresor, and it was a truly remarkable experience.
