Which metal band released the 1989 album 'Operation: Mindcrime'?

Queensrÿche released the 1989 concept album Operation: Mindcrime. The progressive metal record tells a politically charged story about a drug-addicted revolutionary who becomes involved in an assassination plot.

The album uses recurring musical themes and narrated sections to connect its songs into one continuous narrative. Its story examines political manipulation, extremism, religion, and personal loyalty, making it one of progressive metal's best-known concept albums.

Operation: Mindcrime is sometimes confused with Queensrÿche's 1988 album Empire, which contains the band's best-known song, "Silent Lucidity." Fates Warning, Savatage, and Crimson Glory were also influential progressive or technical metal acts, but they did not release this album.
