On the former, and on the ballad "And Then So Clear" he pitch-shifted his voice up an octave, using the gender-changing function on a Digitech Pro Vocalist creating a vocoder-like effect.

His studio features a selection of hardware including a Lexicon Jam Man loop sampler and an Eventide H3000 Harmonizer.

"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 ambient-style "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.

The final track on the album, "Bone Bomb", was inspired by a newspaper story about a Palestinian girl who becomes a suicide bomber.
