Fates Warning is an American progressive metal band, formed in Hartford, Connecticut, in 1982 by vocalist John Arch, guitarists Jim Matheos and Victor Arduini, bassist Joe DiBiase, and drummer Steve Zimmerman. There have been numerous lineup changes over the course of their 42-year career, and Matheos is the only constant member. As of 2020, the band consists of Matheos, vocalist Ray Alder, bassist Joey Vera, drummer Bobby Jarzombek and guitarist Michael Abdow. Fates Warning also had a revolving cast of drummers and guitarists by the time Jarzombek and Abdow joined the band in 2007 and 2020 respectively.

Progressive metal is a broad fusion music genre melding heavy metal and progressive rock, combining the loud "aggression" and amplified guitar-driven sound of the former with the more experimental, cerebral or quasi-classical compositions of the latter.
