* BasedOnADream: Both "Here Comes the Flood" and "Red Rain" were inspired by Gabriel's dreams.
* BlackSheepHit: "Sledgehammer" and "Big Time", in which a singer normally known for combining art rock and world music scores two huge hits with a Stax soul throwback and a funk-rock tune, respectively. In terms of lyrics, both songs (especially "Sledgehammer") also have a much sillier tone than usual for his music. (His later song "Steam" was deliberately given a similar style to "Sledgehammer" in an attempt to ride on the latter's success.)
* CutSong: A version of the song "Burn You Up, Burn You Down", featuring the Blind Boys of Alabama, appeared in the initial pressings of ''Up'' given out to the press for review, but was then ultimately deleted from the CD prior to release. The song would eventually appear on the greatest-hits collection ''Hit'', in a very different mix, with a sound that more resembled the song's first appearance on ''Big Blue Ball''.
* DevelopmentHell: In 2002, Gabriel teased that the next album after ''Up'' could be a double-album of songs named ''I/O''. Consequently, nearly every new song Gabriel has produced to date has been theorized to eventually be included on ''I/O''. Press interviews even up to 2013 still tossed around I/O as a possible new record title. However, in the fall of 2014, as he continued to record new songs, Gabriel began the dial back the idea of I/O and that the next record could take on a different form. The ''I/O'' title, however, has since risen in Gabriel fandom to ''Chinese Democracy'' [[Music/GunsNRoses proportions]], and even has its own page on TheOtherWiki.
* EnforcedMethodActing: Gabriel is really being shocked by the lights he's wearing at the end of the "Sledgehammer" video.
* Creator/{{Hipgnosis}}: Did the cover art for his first three albums.
* MilestoneCelebration: He celebrated the 25th anniversary of ''Music/{{So}}'' with the "Back to Front" concert tour, where he performed the album in its entirety (along with some other well-known songs in his discography).
* NamesTheSame: [[WordOfGod He claimed he was unaware]] that there was a "Barry Williams" who played Greg Brady in ''Series/TheBradyBunch''. until the single was released and it was pointed out to him.
* SimilarlyNamedWorks: ''Up'' shares its name with a Creator/{{Pixar}} [[WesternAnimation/{{Up}} film]] and a {{Right Said Fred}} album.
* WhatCouldHaveBeen: Music/DavidBowie declined to cover one of Gabriel's songs for ''And I'll Scratch Yours''. Granted, we got Music/BrianEno instead (who's pretty awesome in his own right), but it was still pretty disappointing. Music/{{Radiohead}} also dropped out of the project.
** Gabriel's decision not to reunite with the "classic Genesis" lineup in 2007 to tour ''Music/TheLambLiesDownOnBroadway'' may count as well.
* For the film ''Film/SayAnything'' Cameron Crowe wanted "In Your Eyes", Gabriel requested a rough cut of the film before he licensed the song. He told Crowe yes, but that he was disturbed by the overdose at the end. The producers had sent him the film ''Wired'' (a Creator/JohnBelushi biopic) instead.
