When Has Phish Played Acoustically?
Phish has forayed into acoustic performance during four periods, thus far: 1993-1994, 1996, 1998, and 2009.
Shows & Sets: Two entire Phish shows have been acoustic - the Bridge School Benefit shows (10/17/98 & 10/18/98). Those were reported by (the old) Phish.com as "the first entirely acoustic Phish sets in a dozen years". We're not sure what the earlier one(s) was(were), though they have played one acoustic set since: the first set of the third day of Festival 8, 11/1/09.
Mini-sets: Parts of some sets have featured acoustic segments. Late 1994 featured some great acoustic bluegrass, particularly a chunk of 10/18/94 (as well as the 11/19/94 post-show parking lot jam). Mini-stages with scaled-down acoustic setups on a riser were used at 8/5/96, 8/13/96, 8/16/96, and 12/28/98.
Songs: Parts of some songs have sometimes been acoustic, including the opening of "My Friend, My Friend" (primarily 2/3/93 to 4/10/94 ; see chart) and the ending of "Fluffhead" (on 3/12/93, 4/23/93, 5/1/93, and 7/30/93), as well as some instances of "The Horse" (2/3/93 to 4/14/94; see chart), one instance of "Tela" (8/9/93), and, in the fall of 1998, "Driver", "Sleep", "Brian and Robert" (the latter by Phish at Shoreline, and then Trey later in the year), and "Dog-Faced Boy" (11/18/98).
Sideshows: Trey has played acoustic songs or sets outside of Phish, including on his first "solo" tour, occasionally at TAB shows, and in a mini-set with Mike on the GRAB tour.
