Originally forged in 2005 by vocalist, lead guitarist and composer Sigurður, rhythm guitarist Úlfar and drummer Arnar, the band has overcome line-up changes, musical changes and ideological challenges but always reached a higher level of strength. Since then ATRUM has made a significant impact on the Icelandic metal scene with its forceful blend of death and black metal, mixed with Sigurður‘s and Úlfar‘s experience in classical music and, with the parting of Arnar in 2007, it was structurally completed by the addition of Icelands fastest and most prominent metal drummer Ragnar.
