This show was apparently three sets, but only the first set circulates.
Each block is a song. Color = how overdue it was. Brighter = bigger gap relative to average.
Each bar shows how many shows since the song was last played, relative to its average gap. Bar extends past the center line = overdue.
Phish performed 8 songs at Old Stone Church in Newmarket, NH on December 17, 1988. The show lasted approximately 1 hour and 18 minutes. This was part of the 1988 Tour.
