It marks the second Halloween show in which Phish dressed up in a "musical costume" by performing an album from another artist in its entirety. The band, along with a horn section, unveiled a complete performance of The Who's Quadrophenia, led by keyboardist Page McConnell, sandwiched between two sets of Phish's own music. During their performance of "Harpua" Trey Anastasio told the story of Jimmy listening to his favorite album, which happened to be "the very same album that Phish was playing as their Halloween album at Rosemont Horizon that night." At this point they broke into a brief segment of "Beat It" by Michael Jackson, which led to fans believing they were going to play Thriller. They also played a loop of "Wanna Be Startin' Somethin'" over the PA at the beginning of set two before the ocean sounds of "I Am the Sea" overtook it. At the end of the show, the band encored with "My Generation" and destroyed their instruments just like The Who had done thirty years earlier.
