[BIBIO] has made very perceptive observations on this track, and some others:
On colours: [BIBIO] notes that the "yellow" in "Alpha And Omega" seems to repeat continuously at a lower volume; that "Music Is Math" has a faint voice which could be saying "purple", and that playing the end section at half-speed results in what sounds like "red" being repeated. With the "orange" in "Aquarius", they might be trying to cover the range of rainbow colours.
Repeated allusions to flying (in this and other albums): an aeroplane drone in an eagle in your mind; corsair as a type of plane; comments about going to high altitudes for inspiration; "Kid For Today" possibly containing a looped aeroplane drone throughout the track; an interview picture of BoC in an airfield with planes ("the secret life of Boards of Canada photo). Also the interactive scenes on the BoC website: the introductory scene is of aeroplane contrails, and many of the other interactive scenes are flight simulators."Chinook" is a kind of helicopter, among other things.
[Leo B] pointed out that the second occurrence of the phrase is at 2:16 in the track. 216 = 6×6×6. Given all the other references of this kind (such as the album length of 66'06" (666), it is at least plausible that this is no coincidence). However, see below on whether the time IS 66'06".
From the Spanish language Mondosonoro interview, which BoC say that they were really pleased with the beat in this track, which sounds like a taut tope being pulled across the hull of a wooden ship.[1]
[Wikao] notes the sound heard immediately as the track begins may be that of cork being harvested.
At approximately 2:10, a back-masked voice is heard saying "a god with horns" twice to the sound of a crackling fire and a distant church bell. This is sampled from the Channel 4 series Desperately Seeking Something (Series 2 Episode 1)[2] about the Wiccan religion, which is also sampled numerous times in "Dawn Chorus". The episode quotes a poem called The Pipes of Pan, written by Viavianne Crowley in her book Wicca: The Old Religion In the New Age:
The Pipes of Pan In caverns deep the old Gods sleep But the trees still know the lord And it's the pipes of pan, which call the tune In the twilight in the wood The leaves they dance to the goat god's tune And they whisper his name to the winds And the oak trees dreams of a god with horns And know no other king.
Slowed flute from "When the Music Starts to Play" by The Incredible String Band.[3]
4:08 - looped voice saying "take my hand", "to land", or "too late"
On the 2002 website, "take my hand" appears in the scene "seven forty seven". If you fly up to a suitable "pillar" you'll hear it a bit more clearly on its own.
[sandrail] suggests there may be a voice saying "come help me" during the backmasked speech.
