Phish

Phish is an American rock band noted for their extended jam sessions and musical improvisation. Formed at the University of Vermont in 1983, the band's four members performed together for over 20 years until their self-proclaimed breakup in August 2004. On September 30, 2008, the band announced they would reunite for three shows on March 6th, 7th and 8th at the Hampton Coliseum in Hampton, VA.

Their music blends elements of a wide variety of genres,[1] including rock, jazz, bluegrass, and funk. Each of their concerts was original in terms of the songs performed, the order in which they appeared, and the way in which they were performed.

Although the group received little radio play or MTV exposure, Phish developed a large and dedicated following by word of mouth, via Phish.net (originally a mailing list, then a Usenet newsgroup, now a website), and the exchange of live recordings. Rolling Stone hailed them as "the most important band of the 90s" and stated that the band helped to "...spawn a new wave of bands oriented around group improvisation and superextended grooves." [2]
