Polish media revealed over the weekend that frontman Adam “Nergal” Darski of Poland's BEHEMOTH was rushed to the Gdansk Medical University Hospital to receive treatment for an undisclosed illness.

Nergal now checks in with the following update:

"Dear All,

I’d like to announce that Behemoth won’t be able to tour for the forseeable future. I don’t wanna bore you with details here, but I’m sick and am receiving some serious medical treatment.

It’s gonna take another few weeks or more for full recovery, and so we have been forced to cancel all the Behemoth shows in August, planned dates in Russia and Baltic States for September and October and our American tour in November.

I know how much it sucks but health comes first. I can assure all of you that when we return, I’ll be stronger than death, and we’ll reschedule every tour as soon as logistics allow.

I feel good and strong, my mind is focused, I've got my loving woman by my side, my band mates, friends (never thought there are so many, haha), management, agents and label people are giving me massive support. I can’t ask for more but a little patience now.

The fact that we won’t be touring for the next few months doesn’t mean we’ll hibernate. Behemoth will be active on several other levels. In upcoming days you can expect the premiere of our newest video, 'Alas, Lord Is Upon Me' which is by far the sickest fuckin’ thing we’ve ever done!

Evangelia Heretika DVD is coming out as scheduled in November this year. Also, check out our Webstore that opens for international markets in upcoming weeks. This is it for now. Stay tuned!”

As previously reported, Behemoth will be unleashing the group’s second-ever DVD, titled Evangelia Heretika, this fall, 2010. More details, such as DVD content, video clips, and pre-order information will be made available in the coming weeks.

Vocalist and guitarist Nergal comments: “We’ve been through hell and back to make this release happen. I know we only have a few DVD’s in our catalogue so far but they are not even close to what you are gonna experience with Evangelia Heretika! Expect approximately 5 hours of essential Behemoth. Long-time Behemoth artistic collaborator, Graal, has provided us with some of his most disturbing and completed vision to date.”

Evangelia Heretika will be released in North America via Metal Blade Records, in Europe via Nuclear Blast Records, and in Poland via Mystic Records.

In other news, Behemoth recently finished filming and editing a new production video for the track 'Alas, The Lord Is Upon Me', off their latest release Evangelion. The video was produced and directed by Dariusz Szermanowicz and Grupa 13 who also shot Behemoth's videos for 'Ov Fire And The Void' and 'At The Left Hand Ov God'. Stay tuned to Metal Blade TV and Behemoth’s sites for information on when the video will be premiered.
