Big Generator

Big Generator is the twelfth studio album by English progressive rock band Yes, released on 28 September 1987 by Atco Records, their last album of new music for the label. After touring in support of their previous album, 90125 (1983), which saw the band move from progressive rock towards a pop-oriented and commercially accessible direction, Yes started work on a follow-up in 1985 with producer Trevor Horn.

Released on 28 September 1987, Big Generator peaked at number 15 on the Billboard 200 during its 30 weeks on the chart, and at number 17 on the UK Albums Chart.

On 8 December 1987, it was certified gold by the Recording Industry Association of America (RIAA) for selling 500,000 copies in the US. On 29 April 1988, it was certified platinum for selling one million copies. Like 90125, the album earned Yes a Grammy Award nomination for Best Rock Performance by a Duo or Group with Vocal.
