The Grateful Dead Listening Guide has a very eloquent post describing this show, so I’ll refer you there for a more detailed description of this Pacific Northwest performance from 1979.
From my point of the view, the first set of this show is basically a take it or leave it affair. There’s nothing here to write home about, but the opening Mississippi Half-Step>Franklin’s Tower is a good way to start a show and it’s a frequent highlight of 1979 performances.
The big highlight from the second half is the massive Sugaree. On top of that, we’re treated to an unusual post-drums pairing of Stella Blue>Truckin’ and a raucous and even weirder Shakedown Street encore.
The audience recording is pretty good, but for my money the Matrix is better. Here it is: https://archive.org/details/gd1979-07-01.mtx.seamons.95742.sbeok.flac16
