John,
Yes, that's the Botstein/LPO recording of the 1894 Schalk Edition on Telarc – fascinating to hear, but I wish Botstein had used more conventional tempos. His tempos seem to me quite brisk, especially in the Finale. The sound is, as you say, quite spectacular.
As to the Zander recording, more reviews are beginning to come out. Mr. Lipscomb's review in Fanfare is quite positive. Mr. Hurwitz clearly felt otherwise. I continue to hold the recording in high regard, though I do agree that Zander's use of a cathedral floorplan in his analysis is more than a bit silly.
