[1] Vocalist Nemtheanga joined the band after seeing an advertisement for a singer in Dublin specialist metal store The Sound Cellar in 1991.

Although their debut album, Imrama, was characteristic as being in a more melodic black metal musical direction, they gradually came to refine their sound with A Journey's End, which included the use of mandolins and whistles and a more epic style.

The two subsequent releases, The Burning Season and Spirit the Earth Aflame, showed the band's reflection of cultural geist and emotion, woven into an amalgam of black, Celtic, and folk metal musical styles.

In January 2006, the band played their first US show alongside Thyrfing and Moonsorrow at the Heathen Crusade metalfest in Columbia Heights, Minnesota.

The band's sixth album, To the Nameless Dead, was released on 16 November 2007 with universal praise for its raw sound used from the first or second recordings.
