Well, this is really well played, sung, and recorded M8th.
I'd say in recent years I've never heard a M8 that is sung this well - the soloists are all uniformly excellent as are the choruses. SFSO plays the music with smooth but burnished intensity following all of MTT's often challenging instructions. As I suspected, MTT adopts a rather swift tempo in Part I. with a brazingly fast ending. The overall effect is exciting but it is peppered with occasional retardando, eg, "Veni, Ve~~~~Ni Creator ..." at the start of the recapitulation. This stretching of "Ve" is strange and weird because MTT restores the previous tempo immediately following this. Elsewhere, he also employs a few pauses, not all of which are at good spots; there is one near the end of Part II. where the music needs to move forward with a maximum momentum and an uninterrupted flow. He also does another ritardando towards the end of the choral part (where Schwarz accelerated on the contrary).
Part II is slow, as in Boulez and Nagano. But it's not as dragging and the final pages cap up power and catalysis as all good performance of M8th should. Yes, the final orchestral part is all drawn-out out with every detail well caught.
The recording quality raises a concern - although it captures lots of details and is very bright, to my ears the balance & dynamic range shift frequently, and it sounds somewhat claustrophobic without much ambiance. Listen to the very ending of Part I. Its power trails off quickly because there isn't much ambiance that is needed to sustain the tension in both space and time.
All in all, a very nice addition to MTT's Mahler cycle, but I'd prefer Schwarz/Seattle Symphony recording over this one. Although the singing is not on a par with MTT's, the Seattle recording has better tempos, flows more naturally, and is blessed with a conducting that shows much musicality that is sometimes lacking in the MTT's edition.
That's all. I'll need to listen again for a more accurate review.
