History
It is also the first Pink Floyd song credited to Wright/Gilmour since "Mudmen", from the 1972 album Obscured by Clouds.
It was never performed live by the band, though portions of it were included in the sound collage tape played before their 1994 concerts.
Track overture
The noise which opens the track caused some confusion among fans in 1994, who were unsure, on playing the album for the first time, whether or not their copy was faulty, as the noise lasts for nearly 1 minute before any music begins. According to an interview with Andy Jackson, recording engineer for the album, this noise is electromagnetic noise from the solar wind. More precisely, this sound is a very low frequency record of dawn chorus and sferics, radio events respectively due to solar wind interference with Earth's magnetosphere, and lightning strikes radio emissions interfering with Ionosphere; this sound has been mistaken for Earth's crust shifting and cracking.
