Phish is an American rock band noted for their musical improvisation, extended jams, blending of musical genres, and dedicated fan base. Formed at the University of Vermont in 1983 (with the current line-up solidifying in 1985), the band's four members—Trey Anastasio (guitars, lead vocals), Mike Gordon (bass, vocals), Jon Fishman (drums, percussion, vacuum, vocals), and Page McConnell (keyboards, vocals)—performed together for nearly 20 years before going on hiatus in August 2004. 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.
Phish's music blends elements of a wide variety of genres, including rock, progressive rock, psychedelic rock, hard rock, funk, folk, jazz, and blues. Although the band has received little radio play or mainstream exposure, Phish 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.
