Firewind is a Greek power 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 two albums with this current line-up, with new singer Apollo Papathanasio (Evil Masquerade). The demo attracted the attention of Leviathan Records, but activity was put on hold when Gus was hired by Dream Evil and Mystic Prophecy.
