Yep, it's a board...but that doesn't mean much.
Definitely a soundboard recording, probably with an audience mike thrown into the mix for a little flavor. However, this is far from crispy. There are large segments of songs missing in some instances, and the mix is far from perfect.
I was at this show and it was one of the best out of 60+ shows I saw. However, this recording isn't the one to get. I'd suggest
gd87-04-10.nak.braverman.10537.sbeok.shnf as the best available copy of this show, although that show suffers from a slightly weak bass response.
If ever there was a show that called for a multi-source matrix, this is it. A mix of the audience I mentioned above, combined with another audience to fill in some of the bass and this soundboard source (where possible) would really be a great recording. I'd do it myself, but lack the knowledge.
In any event, get SOME copy of this show; the entire night is just amazing.
