I believe the BCT was the last truly small venue the Dead played (Spring '86). I'd have loved to seen the Fall '84 shows there (1st official taper section shows), which were some of the best of that year, not to mention the epic August '72 run.
Here's some trivia, and it's a show I did attend: the first show ever billed as "Phil & Friends" was at the BCT. It was acoustic, with Jerry, Bobby, Phil (on a huge hollow body guitar), and Vince. 9-24-94. It was a benefit for the Berkeley High School music program. There was a very rare, for that era, Duprees Diamond Blues, that Jerry so thoroughly flubbed in a way that only he can. 😀
