eMusic has both of these available already as MP3's, so I downloaded them. I probably won't listen to Gergiev until next week, but quite enjoyed the Eschenbach yesterday. My main gripe is with the utter lack of cymbals throughout. Pretty much all of the other percussion is perfectly captured (great tam-tams big and small, even suspended cymbal), but the cymbals are almost nonexistent. Working backwards in the finale: the organ, tam-tams, and brass are superb at the end, although I would have liked a little more prominence from the bells. The soloists and chorus are superb. The march of the souls suffers a bit from the lack of cymbals (where is that "Whipping" of the souls?) -- but every other aspect is excellent. Eschenbach makes more of the percussion crescendo than most, but MTT has him beat hands down in this section (conversely -- the MTT lacks organ at the end). Eschenbach also makes a lot of the primal scream at the beginning of the finale -- as well as in the Scherzo). Contrast this to the recent Macal, where the screams are total non-events (Note: IMO, the Macal is a big DUD overall). DH's review mentioned the slow second movement, but without looking, I believe that it is faster than Lennie/DG, MTT, and much faster than Lennie/LSO (which IIRC clocks in at over 12'). Also, it doesn't sound all that slow. I'll second DH's mention of the first movements' recapitulation -- which is quite hair-raising due to the strong brass.
As I stated above, I have an MP3 version for now -- so I cannot comment on the sound. But all-in-all, this is quite an exceptional M2, despite my utter disappointment with the lack of cymbals.
