Forming in 1980 this Japanese group made it a habit to clone Western rock music. Their debut mini-album came on the indie 'Medusa' label titled simply Anthem in 1985, with the follow-up album Tightrope following a year later. Influenced by the styles and melodies of U.F.O., Thin Lizzy, Kiss, and later thrash acts like Megadeth, Anthem would complete two more albums, Bound To Break (1987) and Gypsy Ways (1988).
Their first EP single in 1986, Xanadu, was the first known song to be used for promotion of a new video game, that being Nihon Falcom's computer RPG "Dragon Slayer II: Xanadu".
By 1990 there had been several membership changes, settling on Elizo Sakamoto (vocals), Hiroya Fukada (guitar), Nuoto Ski Bata (bass) and Tahamasa Ohuchi(drums), none of whom were original members by the end.
Hunting Time (1989) and No Smoke Without Fire (1990) would follow before their best of compilation, Best 1981-1990 came about. Domestic Booty (1992) and the best of part 2, Best II (1992), and their live album Last Anthem (1992) came before their break-up.
The act's music failed to make an impact on the Western market and remained silent for some time before their reformation under the line-up of Eizo Sakamoto (vocals), Akio Shimizu (guitar), Naoto Shibata (ex-Loudness; bass), Hirotsugu Homma (drums - joined shortly later and replaced Takamasa Oouchi) for the release of Heavy Metal Anthem (2000). Seven Hills (2001) and Overload (2002) followed.
In 2006 the band returned with Immortal, now leaning in a more power metal direction seen more directly on 2008's Black Empire.
Heraldic Device followed in 2011, their last album with record label company 'JVC'.
Burning Oath (2012) and Absolute World (2014) followed, before the last album, however, in February 2014 singer Eizo Sakamoto left for a second time and was replaced by former singer Yukio Morikawa. The group also announced drummer Isamu Tamaru as a permanent member.
