I'm glad to see someone else say that this tape can't be the Golden Hall & has to be a Bay Area venue!
The Euphoria Ballroom is a good guess; that would solve a few problems. The audience noise does sound very similar. There are a few mix differences, though. On the 7/14 tape, each guitar is on its own channel; vocals, bass & drums are in the center. On "8/5," the guitars & vocals are over on one side, and the drums, bass & mandolin are on the other. Also, the audience sounds closer to the mics on "8/5" than on 7/14. (It's harder to estimate the size since the clapping always gets cut right off, but I don't get the impression of distant audience members that I hear on 7/14.) And note that, while on 7/14 we hear the audience mainly just through the (center) vocal mics, on "8/5" it comes mostly from the drums/bass channel - which may indicate a different mic setup. The 7/16 electric set is mixed the same as 7/14 (guitars on two sides, drums/bass/vocals in center). So it would be exceedingly strange if we had a misdated 7/16 acoustic set that had a totally different mix than the Euphoria sets before & after. Not only that, but it would be almost unheard-of for Jerry to perform Candyman in both the acoustic and electric sets on 7/16. So, sadly, I have to disagree with that suggested date. Aside from the mandolin, I only hear the usual 2 guitars & bass on "8/5." Our 7/30/70 tape makes a useful comparison. The mix is exactly the same as on 7/14, to my surprise. The crowd, however, is noticeably smaller than on "8/5" - in fact, it sounds like there's hardly anybody there, and they're not nearly as enthused as the "8/5" crowd. So that may indicate a different venue. I am not sure we can get any closer than "Bay Area venue with NRPS, mid-summer 1970."
