Relayer is the 1974 album by the progressive rock group Yes. It was created after their keyboardist Rick Wakeman left and was replaced by Patrick Moraz. Patrick Moraz's keyboarding style is noticably different from Rick Wakeman's. His playing is a lot freer and syncopated and his synthesizers sound more nasal. The album features three songs. The epic Gates of Delirium is a 20 minute song about war and society. It has an incredible percussion orchestration by Alan White that resembles the sounds of a battlefield. Sound Chaser is a ten minute song that has strong fusion influences and even has the band singing a "cha cha" phrase. To Be Over is a Japanese influenced ballad-like song that eventually turns into a Steve Howe guitar solo.
