Y'know... in concert you've got all of the instrumentation going on as well as the vocals, so the songs sound much better "in person".
Axl didn't do the show a cappella, so the negative comments about the poor quality of his singing are pretty baseless.
Axl was having trouble with his wireless pack all night. So much of the time he couldn't even hear the band. (I can also tell you that during the first part of the encore (like during Madagascar and Better, Axl's voice was almost completely drowned out by the instruments.) There were technical problems with the sound (from the band's point of view) all night. Luckily, the problems didn't really affect what we could hear in the audeince (except for the problems with Axl's volume that I just mentioned.).
The "in-ear monitor" mix is not the best way to hear the show if you want to understand what we all heard in the audience that night. But, since it *is* better than any available audience recordings, I guess it will have to do.
Axl's performance was not "shitty", "horrible", "awful", or any other negative adjective you can come up with. It's just with this type of recording, we're not getting the full picture.
