MTV.com has issued the following report from Chris Harris:

On October 14th, DIMMU BORGIR - who just happen to be Demi Lovato's favorite black-metal band - will release a a three-disc DVD/CD set called The Invaluable Darkness, the band's first visual offering since 2002's World Misanthropy. Boasting live footage shot last year, during gigs in Norway, Germany and England, The Invaluable Darkness demonstrates the unbridled furor of seeing Dimmu live, guitarist Silenoz said.

"It shows the honest rawness and atmospheric darkness of our concerts," the Norwegian told Metal File last week, after dismissing recent online rumors that his band's next LP would be coming out through Roadrunner Records. "Basically, it shows the intense live side of the band, as opposed to the perfection and the cleanness of how we sound on our albums. It's just a different side to the band, basically."

Dimmu Borgir began thinking about The Invaluable Darkness two years ago, but didn't start capturing footage until last summer, Silenoz explained, adding that the band will use its current stint on the Blackest of the Black Tour - which got underway Thursday night in Miami Beach, Florida, and also features the tour's founder, DANZIG, along with MOONSPELL, WINDS OF PLAGUE and SKELETONWITCH - to promote the DVD. Dimmu Borgir will not, however, use the tour to write material for their next LP.

"It's our first time on Blackest, but Glenn [Danzig] had wanted to bring us out before [on the tour], but we weren't available until now," Silenoz said. "We've done Ozzfest before, but we're looking forward to this tour more. We did the main stage on Ozzfest, playing in f--_ing broad daylight. This tour will let us play in bigger places, but at the same time showcase more of what the band's about, visually. We are going to concentrate on the tour for now. Some years ago, we tried putting [material] together on the road, but once we got home, we listened back to it, and were like, 'What the f--- is this?' So, we just scrapped it all. We find it's so much better to totally focus on one thing at a time, and then, when that's over, you move on to the next [thing]. We don't really feel like we need to rush things, anyway, so we'll just take our time, and it's going to be what it's going to be."

Dimmu Borgir hope to reconvene in late December to begin writing the follow-up to 2007's diabolically titled In Sorte Diaboli. "We have some ideas floating around already, but we haven't arranged any material yet," he said. "We'll start doing that once the touring for this DVD is over." The band's frontman, Shagrath, is also due to marry soon - he's engaged to actor Nicolas Cage's ex-girlfriend, Christina Fulton, so that may have an effect on when Dimmu finish their next album, which Silenoz said could be out this coming spring.

"I'm sure [Shagrath] won't let anything get in the way [of] the band - I think, I hope," the guitarist said. "We don't need a Yoko [Ono] situation."
