This was an all ages show listed in the Apr/May 1991 Phish Update. Some fan sources claim this show was cancelled and re-scheduled to 3/25/91. However, Mike Grace (who was recording the surrounding shows) and Mike Lynch, who attended this show, both recall Durango happening as scheduled between the Aspen and Steamboat Springs shows. Mike Lynch recalled driving through a blizzard from Telluride to Durango and arriving to find the band sitting around a piano backstage writing a song before the show. There was reportedly a huge snowball fight after the show. While there is no evidence that it was recognized at the time, this is thought to have been the band's 500th show. There are no known recordings of this show and the setlist (and which song the band was working on before the show) is unknown.
