I really like this performance. So far I have only had a chance to listen to it in the car, but it is certainly a fine complement to the Levine RCA set which lacks M2 and M8. The first movement sounds appropriately 'funereal', and not like 'Mars, The Bringer of War' that we experience with the recent Jurowski, and the last movement sounds really monumental.
Oddly, at the end of the first movement there is no cut off so you hear the audience and musicians for some time, and then the disc just ends. Why they left this in I have no idea. The same thing happens after the second movement. There is about a minute of live sound before the third movement starts. "Urlicht" begins without a pause and there is only a short delay before the final movement begins with an almighty crescendo. The very end of the symphony left me with goosebumps, something that has not happened with any performance for quite a while.
Not having any musical training at all, I can't comment on the standard of playing or singing, sorry.
