Audio quality very good, not great, and a reasonably strong performance
Audio is a bit dark in tonality, and muffled a bit in spots.
If it's a soundboard recording, there was a mic at the board to pick up some of the audience noise.
I think it's much more likely that it's an audience recording and the mic is at the PA stacks.
Groon ends on a laugh... it gets out there, way way way out there.
Lady of the Dancing Water is a lovely (presumed) second encore.
There are certainly other shows from this tour with stronger performances and better audio quality. That said, this is well worth a listen, and much better than most.
