"Perfect Symmetry" is the 5th full-length studio album by US progressive metal act Fates Warning. The album was released through Metal Blade Records in August 1989. Fates Warning was formed in 1982 under the Misfit monicker but changed to their current name in 1984. They underwent quite a musical development on the first four albums, starting out a traditional heavy metal act on "Night on Bröcken (1984)", to a US power/progressive inclined metal act on "The Spectre Within (1985)" and "Awaken the Guardian (1986)", to a hybrid US power/thrash/progressive metal act on "No Exit (1988)". Between the release of the latter two, there was a change on the lead vocalist spot as original singer John Arch was replaced by Ray Alder. A lineup change that brought a significant change to their sound. On "Perfect Symmetry" a new drummer was introduced as original drummer Steve Zimmerman was replaced by Mark Zonder (Warlord). A lineup change that would also have great impact on Fates Warning´s sound.
