Queensrÿche is one the first bands considered to play progressive metal, though they were also important to the US power metal style on their earliest releases. They are most famous for their Operation: Mindcrime (1988) album.
Division in their ranks led to there being two Queensrÿche's between 2012-2014, with the one led by singer Geoff Tate eventually being renamed to Operation: Mindcrime. This list contains both versions, including Operation: Mindcrime releases.
Between them they have released 18 studio albums.
