%22Isolation%22 is a 1980 song appearing on the post-punk band Joy Division's second album, Closer. The song is based upon an electronic drum beat by Stephen Morris, accompanied by a high-pitched keyboard line by Bernard Sumner. Midway through the song, a rushing drum and hi-hat motif come in, propelling the song toward its dramatic end in what resembles a compact disc skipping (though the song predates the format), followed by a sudden electronic crescendo. In his book %22Unknown Pleasures: Inside Joy Division%22, Peter Hook reveals the ending came as the serendipitous result of Martin Hannett's efforts to rescue the original master tape from a botched edit by a junior sound engineer.The song also appears on the Heart and Soul box set and on Permanent. A live version from the band's last concert appears on Still. The song is also used in the 2007 Joy Division biopic Control.
