This week, David Gans curates the setlist as Garrin, Steve, and Jeremy duke it out for the Guess the Year crown. This is the first part of a marathon finals matchup. Part two comes out next week.

David's new book "Improvised Lives: Grateful Dead 1972-1985", which features photographs and stories, is available now. You can also check out David's regular live streams, where he plays Grateful Dead tunes, folk, country, and beyond, here.

As always, thanks to 30k ft for drawing the poster.
