I usually go with Jeremy Soule's Elder Scrolls score (Morrowind and Oblivion) and throw in some background metal such as Isis, Yob and Neurosis, also The Sword in fast paced fights. Yesterday the players had some intense encounters with barbarians on Storval Plateau on their way to Kodar mnts. and I put on Anonymus by Tomahawk (Native Indian theme on that album) worked pretty good.
