Ed O'Brien of Radiohead, Brandon Boyd of Incubus, and reggae musician Matisyahu. Phish's festival events in the 1990s inspired the foundation of the Bonnaroo Music Festival in Tennessee, which was first held in 2002. Co-founder Rick Farman, a Phish fan, consulted Phish managers Richard Glasgow and John Paluska about festival infrastructure during the early stages of planning. The festivals also inspired other jam band-oriented concert events, such as the Disco Biscuits' Camp Bisco, Electric Forest Festival, and the Big Ears Festival. While Phish has had eight of their singles appear on Billboards Adult Alternative Songs chart since its inception in 1996, even the band's most successful songs would not be recognizable to the average music listener.

The BBC listed Phish as one of "Eight smash US acts that Britain never understood" along with fellow jam bands Dave Matthews Band and Blues Traveler. In describing the band to a British audience, BBC journalist Stephen Dowling wrote "Attending a Phish gig has become a rite of summer passage for American teens in the same way that attending Glastonbury has for British teenagers." Phish has performed 72 concerts at Madison Square Garden since their debut performance there in 1994. Along with Elton John, Phish are tied for the second-most concerts at the venue by a musical act, behind only Billy Joel. In 2019, Billboard ranked Phish as the 33rd highest-grossing concert touring act of the 2010s.
