Phish has been played on NTS shows including The Cosmic Principle w/ Nick Mitchell Maiato, with Sand first played on 14 March 2017.

Phish is a rock band which formed in 1983 in Burlington, Vermont, United States. For most of their career, the group's lineup has consisted of Trey Anastasio (guitar, vocals), Page McConnell (keyboards, vocals), Mike Gordon (bass, vocals) and Jon Fishman (drums, vocals, vacuum cleaner).

The band is known for musical improvisation, extended jams, blending of genres, and a rigorous touring schedule that draws a famously dedicated fan base. Their music blends elements of a wide variety of genres, including funk, progressive rock, psychedelic rock, folk, country, jazz, blues, bluegrass, and pop. Phish were part of a movement of improvisational rock groups, inspired by the Grateful Dead and colloquially known as "jam bands", which gained considerable popularity as touring concert acts in the 1990s.

After 15 years of performing together, Phish went on hiatus in 2000. They resumed touring in December 2002, but disbanded in 2004 after a farewell performance at their Coventry Festival in Vermont. They reunited in March 2009 for a series of three consecutive concerts played in the Hampton Coliseum in Hampton, Virginia, and have since resumed performing regularly.

Although the group received little radio play or MTV exposure, Phish developed a large following by word of mouth during the 1990s, particularly through fan-record tapes of their concerts, which circulated for free online with the band's permission. While often compared to the Grateful Dead, Phish finds their roots in styles such as jazz, funk and alternative rock as opposed to the Dead, who were more influenced by folk, country and blues.

Each Phish concert is different in terms of the songs included and the order in which they appeared, and (for many songs) in the way in which they were performed. Also unique to Phish are their large summer festivals which draw upwards of 70K people to remote areas in Maine and New York State as well as close to 100K for their epic Millennium Show in the Everglades of South Florida.

Along with Bob Dylan and The Beatles, Phish were one of the first bands to have an Internet newsgroup - rec.music.phish - launched in 1991.

In regards to Phish, Rolling Stone magazine proclaimed "Given their sense of community, their ambition and their challenging, generous performances, Phish have become the most important band of the Nineties."
