What are the best shows only available in AUD recordings?

I recently listened to 7/21/74 because Dick Latvala listed it as one of the absolute best shows of that year, and it was pretty great. I also heard 5/8/70 and 12/16/78 recently and I was really blown away by them. 5/8/70 is the lowest sound quality show I’ve ever heard and yet it was well worth the listen, especially the Dark Star > Dancin.

I’ve always avoided AUD recordings since there are plenty of SBD’s I’m yet to hear, but there’s definitely some great shows I am missing as a result. So, what are some AUD shows you guys have heard that you really love?
