Phish

Phish is an American rock band noted for its musical improvisation, extended jams, exploration of music across genres, and devoted fan base. Formed at the University of Vermont in 1983, the band's four members performed together for over 20 years until an official breakup in August 2004. The band reunited in 2009 for three shows at the Hampton Coliseum in Hampton, Virginia, and have resumed their former activities with a full summer and upcoming fall tour, a new album entitled Joy, and a planned October festival in Indio, California.

Their music blends elements of a wide variety of genres, including rock, jazz, progressive rock, psychedelic rock, funk, bluegrass, reggae, country, blues, and classical. Each of their concerts is original in terms of the songs performed, the order in which they appear, and the way in which they are performed.

Although the band has received little radio play or mainstream exposure, it has developed a large and dedicated following by word of mouth, the exchange of live recordings and selling over 8 million albums and DVDs in the United States. Rolling Stone stated that the band helped to "...spawn a new wave of bands oriented around group improvisation and superextended grooves," calling them "the most important band of the Nineties."
