Not sure how I missed this and I apologize if this has already been posted, and thanks to fellow poster Raising Iron calling me last night to alert me about this, the Sons of Northern Darkness, Immortal, has announced a mini tour for early 2011. 
The following was taken from the Immortal website and the post date was Wednesday the 17th.
Stoked to see them in Chicago at the Bottom Lounge on February 22...the perfect time of year to see them. Oh, and by the way, they will be with Absu!!! Finally get to see Proscriptor in action. Interesting collection of cities too...
