Another "authentic" version is a live recording (made by Jos van der Linden) with the composer authorizing the balance between the organ and the soundtracks, made in the Grote Kerk in Haarlem on 29 June 1993.
Finally, a recording (also made by Jos van der Linden) of a performance at a Ton Bruynel festival in the Nicolaaskerk in Utrecht on 15 May 2008. This time, Rene Uijlenhoet supervised the balance between the organ and the soundtracks.
Comparing the three versions now, I prefer both the Vught and the Utrecht versions. The former because of its clarity and detailed expression, the latter because of its ambiance, in which the organ and the electronic part combine very well, while the space remains bright and clear (the Haarlem version sounds a bit hollow).
