Firewind is a Greek heavy metal band that was originally created as a way for guitarist Gus G. to market his demo album Nocturnal Symphony in 1998. They became a full band over three years later when they recorded Between Heaven and Hell. The band line-up changed between each album until the final change after their fifth, Allegiance. They have recorded three albums with this current line-up, with new singer Apollo Papathanasio (Evil Masquerade). Drummer Mark Cross was succeeded by Michael Ehre (Love.Might.Kill) after recording Days of Defiance.
