"Under" is a nearly-identical version of a song that was on the unreleased 1991 album My Squelchy Life, which was released in 2014 as a bonus disc with a reissue of Eno's 1992 Nerve Net.
For the ambientesque "A Long Way Down" Eno manually synchronised his vocals with an out of time keyboard melody, and on "Going Unconscious" he went back to using Koan generative music software for the textural background.
