This is another good show from 1977, but the audience recording quality is not the best and things are muddy throughout. Luckily, the show has been commercially released as the first volume of the Grateful Dead Download Series if you want to hear the crisper soundboard recording.
Highlights from this show are the first set Mississippi Half Step and, dare I say it, Looks Like Rain. In the second set, we have a Scarlet Begonias>Fire on the Mountain (pretty good) AND a St. Stephen>Not Fade Away>Stella Blue>St. Stephen (great). It’s pretty awesome to hear Stella Blue transition back into the St. Stephen, an unusual pairing to say the least. On top of that, Terrapin Station is the encore.
