The Wall of Sound played havoc with the Grateful Dead's 1974 summer show 45 years ago due to the sheer time to take apart, transport and reassemble the speakers.
It is appropriate then, on a couple fronts, that this three-disc set concludes a near thirty minutes of untitled jam immediately preceded by a quarter hour of rhythm guitarist Bob Weir's "Weather Report Suite."

You can take 50 minutes of set two between Sugar Magnolia and Sunshine Daydream and simply write Weather Report>US Blues. But the > in the middle is a once-only highlight of the Grateful Dead's entire career.
Obv the Dead loved Massachusetts in June (or anytime). But this is my favorite Mass Dead ever.
