(Sorry if this seems a bit anachronistic; I started it about 6 hours ago, got distracted, and came back to find it sitting here unposted.)
The problem, studiorecluse, lies not in naming a song where Jerry is brilliant, it lies in naming A song where Jerry is brilliant. There are literally thousands of shows available, and hunderds of examples of some of these songs. I could say listen to The Other One, but which version? In a way, because of the nature of the band, you have to have some experience with the music to fully appreciate what it is they are doing. As an analogy, in the context of conversation, if someone makes a relevant quote and you are unfamiliar with what's being quoted, it loses some of it's significance. Also, the music, and this song in particular, evolved heavily over the course of 30 years. Listen to a bunch of examples of The Other One, and you'd have a much better idea. The easiest way to do that would be to go to
www.archive.org , go to the Grateful Dead section, and start reading show reviews to find people's favorites. Maybe some others will offer suggestions as well? I will start you off with two, 4.5.91 (streamable only) and 4.2.90 (available for download).
