Relayer

Relayer is the seventh studio album by the progressive rock band Yes. Recorded and released in 1974, it is the only Yes studio album to feature Patrick Moraz, who replaced keyboardist Rick Wakeman earlier in the year.

History
After the ambitious double-concept album Tales from Topographic Oceans, Rick Wakeman left Yes to resume his solo career. The band auditioned several prospective replacements, the closest contender being the Greek keyboardist Vangelis. He did not become a member of Yes, but these auditions paved the way for several future collaborations between Vangelis and Jon Anderson. The band finally chose Swiss-born Patrick Moraz as a replacement while this album was well into production. The album title comes from the lyrics of “The Remembering (High The Memory)” from Tales from Topographic Oceans.
As with most of Yes’ previous albums, Relayer features artwork by Roger Dean. The CD release features two additional paintings by Dean.
Relayer has the same song format as 1972’s Close to the Edge—a long epic on the first side, and two nine-minute pieces on the second—but employs a radically different musical style. “The Gates of Delirium” is a dense, 22-minute piece that was inspired by Leo Tolstoy’s War and Peace. It features lengthy improvisations by each member of the band, sometimes clashing intentionally with one another. Featuring lyrics about the futility of war, it remains one of the most musically aggressive songs ever produced by the band.
