Trial By Chaos has 2 Hammerfall concerts.

HammerFall is a Swedish power metal band from Gothenburg. The band was formed in 1993 by ex-Ceremonial Oath guitarist Oscar Dronjak. HammerFall was formed when rhythm guitarist Oscar Dronjak quit Ceremonial Oath and invited Jesper Strömblad (from Ceremonial Oath and In Flames) to join him as a drummer in a new musical project he had been contemplating for some time. Dronjak had already composed the song "Steel Meets Steel," which was later included on HammerFall's debut album.
