"Echoes" is a song by the British progressive rock group Pink Floyd which appears on their 1971 album "Meddle". It runs for 23 and a half minutes and is considered by many to be one of the band's finest post-Syd Barrett, pre-"Dark Side of the Moon" compositions.
Although the intentions of the band are unconfirmed, Echoes is commonly enjoyed while synched with the "infinity" segment at the end of Stanley Kubrick's…
Overhead the albatross hangs motionless upon the air
And deep beneath the rolling waves
In labyrinths of coral caves
The echo of a distant tide
