Gems from archive.org?

I haven't generally used archive.org much for Dead shows, but I'd like to dive in. I'm spoiled by having access to the Dick's Picks (and other) series, so to have this vast array of shows is somewhat overwhelming. Can anyone suggest some gems from archive.org? Are there certain shows that are clearer/more enjoyable than others in terms of sound quality?

I guess I'm sort of looking for a short list of archive.org shows to start off with before branching out into individual tapers' collections, etc. Thanks!
