The music is listening
Play on you tube
This is another in the famous show series aka Dicks Picks 24. AKA The Sound Check.
Sadly this is the last of the three Playin in the Band>Uncle John's Band>Morning Dew>Uncle John's Band>Playing in the Band shows. They almost couldn't get the initial Playin out of first gear.
The other other show ever with Playin>UJB>songs>UJB>Playin (aka Double sandwich) will occur in six years up in Lewiston, Maine.
As with all 1974 shows this one is FAB. And it comes with lots of newspaper and magazine coverage which you can read here. Have fun as usual.

Healy and the Grateful Dead became willing guinea pigs for John Meyer, then of McCune Sound; Ron Wickersham of Alembic; and others on the scene who were looking for ways to deliver music painlessly and efficiently at the often ridiculously high SPLs of the San Francisco sound and rock music in general.
“Those guys were long in the design and prototype area,” Healy explains, “and we were long in the criteria. We built a system and scrapped it, built another one and scrapped it. We never had a finished system, because by the time we’d get one near completion it was obsolete in our minds, and we already had a new one on the drawing boards.”
The concept of speaker synergy and phase coherency in particular was understood by the early Seventies, and several designers had come up with ways of implementing it. John Meyer and McCune Sound developed a three-way, tri-amped single-cabinet system with crossovers that reduced phase shift considerably. It was a significant improvement, but there was plenty of work yet to do.
While Meyer was in Switzerland studying every aspect of speaker design, acoustics and the electronics of sound, Healy and Alembic and the rest took off in other directions.
The Dead debuted a new system at San Francisco’s Cow Palace on March 23, 1974, in a concert dubbed “The Sound Test.” Bassist Phil Lesh calls it the “rocket gantry” and maintains that it was the best PA the Dead ever had.
“It was the ultimate derivation of cleanliness,” Healy explains. “No two things went through any one speaker. There was a separate system for the vocals and separate systems for each guitar, the piano, and the drums. You could get it amazingly loud, and it was staggeringly clean, cleaner than anything today. It still holds the record for harmonic and most especially intermodulation distortion.”
Healy calls this system’s theory of operation the “as above, so below theory. If you stack a bunch of speakers vertically and stand close to one, you hear the volume of that one speaker. If you move a little farther away, you hear two speakers; move away some more and you hear three. If you have a lot of them stacked up high, you can move quite a ways away and the volume stays the same.”
There was no mixing board in the house. Each musician controlled his own instrumental volume, because his speaker stack was its own PA system.
Guitarists Bob Weir and Jerry Garcia each had about 40 12-inch speakers in vertical columns, and bassist Lesh had a quadrophonic system. Vocals also were delivered to the band and the audience by the same speakers. Each singer had a pair of mikes, wired out of phase so that background sound arriving equally at both was canceled, while what was sung into one mike was passed on to the amplifier.
