Heimdall - Slough Feg is great, however I have only heard Down Among Deadmen but I think I will go grab the others now.

But when it comes to the Power stuff I prefer the Viking'ish mixed stuff, Einherjer is ok but it is kind of plain. Falkenbach is awesome, Stormlord is great Italian Blackish/Power Metal. Otyg is pretty good especially if you like Vintersorg, same with Isengard/Storm if you like Darkthrone and Wongraven if you like Satyricon. Suidakra is definately A+++ and worth checking out as well, Emprise to Avalon is truly magnificent.
