I've received an advance, promotional copy of the Gergiev Mahler 8. It's interesting, and not all unsuccessful, considering that Gergiev had to hold everybody together in the unbelievably "boomy" acoustics of St. Paul's Cathedral. Unison passages, such the big "block" choral passages in Part 1, aren't such a problem. Instead, ensemble work comes a little loose during the swifter and lightly scored, somewhat Mendelssohn-like passages in Part II (such as after the childrens chorus' first entrance in Part II). But to compensate for that, the childrens chorus is excellent; the best I've ever heard in any M8 (and I think they get reinforced here and there by women's voices). Just to cite one example, you can really pick out the childrens chorus through all that dense polyphony near the end of Part 1. The mostly slavic cast of soloists is fairly successful too.
On the whole, the women are better than the men. The tenor is OK, but not the very best either (I like Johan Botha on the Boulez). But at least he doesn't sound strained on his top notes. One strange thing is that the bass-baritone has a brighter timbre to his voice than the regular baritone. As you might expect, the organ is "kick-butt" throughout. If Boulez had too little organ at the end of his Part II, Gergiev has all the organ anybody could ever hope for. Unfortunately, the offstage brass are too distant to have any effect on the recording. I'm sure that if one had been seated near where the offstage brass were placed, you'd probably hear too much of them. But considering, there's really little to complain about here. My own personal-prefernce complaint is the same one that I almost always have: Gergiev is simply too swift with the very, very end of the symphony (where the simultaneous cymbal/tam-tam smashes are located). But at least there's tons of organ, and the "hang-time" after the final chord - after both parts, really - has to be heard to be believed! That alone makes it fun.
Keep Boulez for clarity within a good acoustic, as well as decent singing (the tenor is great). Keep Bertini for his great tempo relationships and unbelievable ending (super slow with great tam-tam smashes). Keep whatever your favorite Mahler 8 is. Add Gergiev if you want a great childrens chorus (for once) and tons of organ, caught in "one-off" event at a huge cathedral. And yes, it fits on one disc.
By the way, I sampled sections of the new Ivan Fischer M4 on Channel Classics, and it really sounds great. More on that later this week.
