Yes - Drama (1980) {1990, Japan 1st press}

Drama is the tenth studio album by the English rock band Yes, released on 18 August 1980 by Atlantic Records. It is their only album to feature Trevor Horn as lead vocalist, following the departure of Jon Anderson and Rick Wakeman in March 1980 after unsuccessful recording sessions for a new album in Paris and London. Horn was joined by keyboardist Geoff Downes, his partner in the new wave band The Buggles. Drama was recorded in a short amount of time as a tour was already booked prior to the change in personnel. It marked a departure in the band's musical direction with songs more accessible and aggressive, and featuring the use of modern keyboards and a vocoder. ~ Wiki

For this one album, ex-Buggles Geoffrey Downes and Trevor Horn were drafted in to replace Jon Anderson and Rick Wakeman. It rocks harder than other Yes albums, and for classically inclined fans, it was a jarring departure; but it was a harbinger of Yes and Asia albums to come. A newly emboldened Chris Squire lays down aggressive rhythms with Alan White, and Steve Howe eschews his usual acoustic rags and flamenco licks for a more metallic approach, opting for sheets of electric sound. Prime cuts include the doom-laden "Machine Messiah" and the manic ska inflections of "Tempus Fugit." Despite the promise of this new material, the band soon fell apart; Horn went into production, Howe and Downes joined Asia, and Squire and White toyed and then gave up on a pair-up with Robert Plant and Jimmy Page, which was to be titled XYZ (i.e., Ex-Yes and Zeppelin). ~ Paul Collins, All Music
