This was was Phish's 1st show at Red Rocks, a historic uncovered amphitheatre opened in 1906 in the foothills of the Rocky Mountains with a capacity of 9,400. The venue is located inside Red Rocks Park which is a city of Denver facility purchased in the 1920's. There was a lingering thunderstorm during the day that ended just before showtime, no doubt helping inspire The Divided Sky opener. Trey's narration during Harpua focused on the history of Red Rocks and on "Harpua" the giant Red Rocks Iguana, who was turned to stone by the deadly gaze of "Posterus Nutbagus" but was discussed throughout the show. Harpua also included a tease of Rock And Roll Part 2. This show featured the summer's first performance of The Wedge. Before Ginseng Sullivan, Trey had did some extra tuning and then said "I'd like to dedicate this song to Brad Sands, the guy who tunes my guitar." Page responded with the Charge fanfare. This rendition of Ginseng Sullivan was performed by Trey on acoustic guitar, Mike on upright bass, Page on piano (introduced by Trey as the "Chairman of the Boards") and Fish on Madonna washboard. Run Like An Antelope contained The Simpsons secret language and a Can't You Hear Me Knocking jam. Slave To The Traffic Light was reportedly enhanced by a lightning storm that could be seen over Denver. Trey played the beginning of My Friend My Friend on acoustic guitar. Purple Rain featured Mimi Fishman on her eighth vacuum solo with Phish, which duties she shared with Fish after having limited success in her Mountain West debut. After this show, the band and crew traveled 544 miles overnight to Salt Lake City, Utah.
