No official confirmation yet, but Kerrang! reported this week that Dimmu Borgir will be co-headlining with Lamb of God at the February 8th Mandella Hall gig.
Will let you know as soon as promoter says one way or t'other; this could be one very, very noisy gig :)
ADDENDUM: No confirmation from promoter - spoke to a staffer at Kerrang! today who said they 'assumed' it was another date on the Metal Hammer sponsored Defenders of the Faith 2 tour with DM. It's not listed as a DM tour date on their official site...any update we'll post here
