Near the end of this song is an aural collage of shortwave radio noise. Morse, teletype, and various data signals can be heard including a radio modem (called the Harris RF-5710) used by hobbyists and naval military services. The Morse code heard at 05:20 decodes to "CQ de GM3DP" (a Scottish callsign). A further noted Morse call-sign was interpreted as 'GM3DSK', discovered by Twoism user 'akrotiri'. He also noted that despite a search for the owner of the call-sign initially yielding no results, when removing the 'M' (allegedly a callsign extension used in Scotland), the call-sign can be traced back to the name 'Ra Lord'. It has been speculated that as 'Ra' (Egyptian sun god) takes on the form of a bird in mythology, it relates neatly back to the title of the track - 'Slow This Bird Down'. A second check of UK records showed the GM3DSK callsign to belong to an individual with the initials R. A. Lord, suggesting the connection is pure coincidence.
"Slow This Bird Down" is pilot jargon for reducing speed during a landing.
The vocalist Solange sampled this track in its entirety on her 2008 album: Sol-Angel and the Hadley St. Dreams. Using the track as a basis for multi-layered vocals, she even referred to the original title in the title of her adaptation: "This Bird".
