Great. Now they can go back and dub in the new organ for:
M2 - Bruno Walter, 1948;
M2 - Maazel/Sony (I think they might have dubbed in a different organ on this one anyway)
M2 - Abbado/VPO/DG (this one has almost no organ)
M2 - Boulez/VPO (again, almost zero organ)
M8 - Maazel (they used the Boston organ, but it's still too little)
Thanks Vienna for screwing up so many Mahler recordings that require an organ. Thanks to those conductors to agreeing to such sub-standard facilities. I no longer own any of those recordings above, and won't unless somebody fixes their wimpy organ sounds.
The Mehta/VPO M2 was recorded in the Sofiensaal with an electronic organ, while the Kaplan/VPO M2 has the Berlin Philharmonie organ dubbed into it.
