"One of These Days" is an instrumental composition used as the lead-off track of Pink Floyd's album Meddle. It begins with the sound of wind and two alternating bass guitars playing single-note parts through an echo chamber and expands to include a recurring organ figure, drums, and finally aggressive lead guitar playing. Three and a half minutes into the six-minute track, drummer Nick Mason is heard declaring, "One of these days, I'm going to chop you into little pieces" in a distorted voice as the music builds ominously, only to recede back to the sound of wind. Pink Floyd first played the song in France on June 12, 1971, more than four months before it was released on record. Upon the release of Meddle on October 30, 1971, "One of These Days" became a favorite of FM radio programmers, its spacy sound seeming to typify Pink Floyd's style. The album spent more than a year in the charts and eventually sold over two million copies in the U.S., helping to set the stage for The Dark Side of the Moon. Pink Floyd was seen performing the song in an empty amphitheater in the 1972 film Pink Floyd Live at Pompeii. The group continued to play "One of These Days" in its shows of the early '70s, but later retired the song. It was reissued as the lead-off track of the compilations A Collection of Great Dance Songs (1983) and Works (1985). After Pink Floyd was reorganized in the early '80s, the band reintroduced "One of These Days" on its tour promoting its 1987 album, A Momentary Lapse of Reason, and used it as the lead-off track of the second CD of the resulting concert album Delicate Sound of Thunder (1988). It was also featured on the video Pulse (1995), which chronicled the tour promoting 1994's The Division Bell, though it was not included on the Pulse CD.
