Notes: (****) Although the album is credited to all five band members, that is a simplification of their relative contributions. Following Rick Wakeman's departure from the band, Anderson/Howe/Squire/White worked on writing Relayer while looking for a new keyboard player. Various people were tried or considered, notably Vangelis, before the band chose Patrick Moraz and by the time Moraz had joined, much of the album had been written. In a Jan 2020 interview, Howe said:

When Rick quit after Tales we regrouped and tried playing with Vangelis for two weeks but we weren’t playing Relayer, we hadn’t written it. As we got ready to go to the studio, and we discovered Patrick, then we became a complete unit and the writing sort of pours into it. Jon and I had written To Be Over and the other music came about through the other collaborations in the studio.

Moraz has described how his first recording session in Aug 1974 involved the band playing him the first part of "Sound Chaser". Anderson asked for an introduction to the piece, which Moraz composed there and then. The introduction was recorded in a few takes after Moraz had explained their parts to Squire and White.

"The Gates of Delirium" was primarily composed by Anderson, while "To be Over" was based on a piece by Steve Howe ("The Serpentine", released on Homebrew 2), then expanded by him and Anderson.

On a Sirius XM interview on the 2017 Cruise to the Edge, White said for the album, "We built a whole percussion tree out of pieces of cars, like springs and stuff" for "The Gates of Delirium". (HP, 12 Feb 17; updated 6 Jan 20)
