The track "Moonloop" is an edited and overdubbed version of a 40-minute improvisation by the full live band recorded at the Doghouse studio on 28 June 1994; a section unused on the album featured a drum beat that would go on to form the basis of "Stars Die."

Wilson remixed elements of "The Colour of Air" for use in the track "Fuse the Sky" during the Signify era on an ambient compilation; it later appeared on Stars Die: The Delerium Years 1991–1997.

The guitar progression of "Spiral Circus" would be reused by Wilson project No-Man for "Something Falls," a b-side from the 1998 Carolina Skeletons single, released before their 2001 album Returning Jesus.

Besides the addition of "Stars Die", the different running order and the removal of "Prepare Yourself", the version of "Moonloop" on this edition is less than half the length of the one on the UK release.

The song "The Sky Moves Sideways (Alternate Version)" represents outtakes and a work-in-progress mix of the original vision of the album as a single 34-minute track.
