“Cavern” has been a rock in Phish’s rotation since early 1990. While most fans have become accustomed to the song as a set-closer or encore, initially it was much more versatile, appearing just about everywhere in the setlist. It was only beginning in 1992 that the band began utilizing it in its current role. In fact, beginning in fall 1992, well over half of the performances of “Cavern” have come either at the close of a set or during an encore. And no wonder: the song’s straight-up rock feel and fist-pumping climax make it a fitting exclamation point on the end of an evening of more excursionary jamming.[1]
