Wow, great stuff and also so unexpectedly bad. It's probably because of the mixing of this recording(?) but man, they were off at times. "Papercut" had terrible levels (never heard these string sounds Joe made at the end, especially not that loud), Chester messed up the first chorus of "Don't Stay", Mike's guitar went dead during "Somewhere I Belong" and overall Brad's guitar volume was waaaaay too high which didn't help the overall performance. Speaking of high, Chester was very likely far from sober that evening. Still he performed greatly!
All in all, I can see why something in the sense of "just destroy the tapes" might have been said at some stage. I don't think the band wanted to go through this performance again immediately after it happened and then might have just forgotten about it (I mean, they forgot about "Lost" being ready and done, so...).
Nonetheless having more of it is awesome and the changed setlist plus "Nobody's Listening" are much appreciated. Great mash-up, just terrible mixing.
