OK, I added Real Player to my computer, just so that I could hear these bloody excerpts. Yes, it seems to be a decent sounding organ; not huge, but with a nice tone. Since it was recorded in the Jesus Christus Kirche (church), the sound and balances seem pretty good to me. I really like the playing and sound of the Staatskapelle Berlin: they're not as dark and heavy sounding as the Vienna Phil.; nor are they as slick sounding as the Berlin Phil. can often-times be. To me, they sound a bit similar to the Staatskapelle Dresden, or DSO Berlin. All of the soloists seem decent too, with tenor Johan Botha sounding particularly good. The only thing I'm concerned about are Boulez's consistantly slow tempi. He tends to unify tempo relationships - minimizing tempo contrasts from one section to the next. Anyway, it does sound promising. There's certainly plenty of exacting detail.
The European version is going to available from HMV Japan by the middle of the month. The Japanese version - which John claims often times sound better than domestic versions - doesn't come out for another few weeks after that. I'm not sure what to do, if anything.
