HammerFall is a power metal band from Gothenburg, Sweden. The band was formed in 1993 by ex-Ceremonial Oath's guitarist Oscar Dronjak and Jesper Strömblad from In Flames as just another musical project.
The music of HammerFall is power metal but not so much emphasis on speed like that of bands like Firewind and DragonForce. Lyrics are of fantasy. The singing style is somewhat similar to 80s style of power metal, reminiscent of Kai Hansen of Helloween. Hammerfall have a sound influenced by bands like Iron Maiden and Judas Priest.
