It's a great set of songs and the sound quality is indeed excellent. Interesting high-pitched flourish on Waiting Room that is presumably a guitar but almost sounds like a piano. The audience can be heard clearly but in a positive way that adds to the enjoyment, for instance people start clapping along in Suggestion which I don't remember hearing before. This show includes 23 songs, clocks in at 1h 33m and is definitely worth your time.

This show has been rated as having 'Excellent' sound quality but it doesn't seem to be available yet. What recording does the sound quality rating refer to?

I used to have an audience recording of this show. It was one of the first Fugazi shows I ever heard, and I still compare every other show I hear to it. Can't wait until it's available.
