Undermind is the eleventh studio album by American rock band Phish, released on June 15, 2004 by Elektra Records.

The introductory passage of "Scents and Subtle Sounds", which opens the album, is taken from a demo recorded by Phish frontman Trey Anastasio and the band's primary lyricist Tom Marshall.

[4] Early copies of the album included a DVD with the 25 minute documentary Specimens of Beauty, a behind-the-scenes film on the making of Undermind, directed by Danny Clinch.

[5] Many reviews praised "The Connection", calling it "the most commanding" and "most commercially accessible" song of Phish's recording career to date.

One month before the album's release, Anastasio (and separately, McConnell) announced on Phish.com that the band would split following their summer tour.
