Similar to the Dark Side of the Rainbow effect (Dark Side of the Moon Album played over The Wizard of Oz film), some listeners suggested that Pink Floyd’s “Echoes” synchronizes with Stanley Kubrick’s 1968 film 2001: A Space Odyssey when played concurrently with the final segment (titled “Jupiter and Beyond the Infinite”).
“Echoes” was released three years after the film’s production and is 23 minutes and 31 seconds in length, quite similar to the “Infinite” segment. Sound effects in the middle section of the song suggest to some listeners the feeling of travelling through, or flying over, an alien world. The drone vocalizations heard in the final scenes of 2001 seem to match with the discordant bass vibrations in the middle of “Echoes” as well as the choral glissandos of its finale. Some argue that there are moments when the song and film soundtrack are nearly indistinguishable. Another notable link occurs during a change in scene at precisely the moment when guitar and keyboards crescendo as the lyrics re-enter for the final verse. The early lyrics contain references to planets, which seems entirely suitable for the film’s depiction of Jupiter and its moons.
The bands has denied any intentional correlation. Watch and decide for yourself….either way, it is a most enjoyable combination, and an epic song.http://www.dailymotion.com/videoxfiqt
