To commemorate the milestone, the band—consisting of guitarist Steve Howe, drummer Alan White, bassist Billy Sherwood, keyboardist Geoff Downes, and lead vocalist Jon Davison—completed the 50th Anniversary Tour across Europe and the United States between March and July 2018.

[2][3][4] The five were joined by American drummer Jay Schellen, who performed the majority of Yes's live sets since 2016 while White recovered from surgery and a bacterial infection that affected his playing.

[6] This particular leg featured guest performances from former keyboardists Tony Kaye and Patrick Moraz; Kaye joined the group for the encores ("Yours Is No Disgrace", "Roundabout", and "Starship Trooper") and Moraz plays on "Soon", the closing section to "The Gates of Delirium".

The album was available as a 2-CD and 4-LP set, along with a colored vinyl pressing limited to 1,200 copies.

Stephen Thomas Erlewine of AllMusic gave the album three out of five stars and noted that it "adheres most closely to the prog rock that made their name in the early '70s" and that the current incarnation of the band "does this sound justice, which makes the album precisely what it's intended to be: a celebration of a particular time and sound, delivered with affection and skill".
