Blackened death metal masters Behemoth have hit their fans with two big announcements. Frontman Nergal has revealed that he is endorsing Demon Energy Drink, with a portion of the proceeds going to the cancer organization DKMS Americas, and that Behemoth will begin rehearsals for their next album in September.

Nergal was diagnosed with leukemia in August of 2010, shocking the massive, worldwide Behemoth fan base. Luckily, Nergal's health has been improving thanks to a bone marrow transplant, and the frontman has decided to use his status as a beloved musician to raise money for DKMS, a non-profit organization that helps leukemia patients in need of bone marrow transplants. .

Nergal recently spoke about why he decided to endorse Demon Energy Drink. "Well, I decided to accept the offer to be a face of this energy drink called Demon," says Nergal. "I've never been much of a fan of such drinks but I loved the idea behind it… the whole campaign is strongly connected with DKMS foundation (the one that found a bone marrow donor for myself). [A] percentage of sales will be donated to the foundation and will make this whole business worthwhile for me. Besides, I loved the name and a logo…so why the f--- not?"

The Behemoth frontman also took the opportunity to speak about the band's upcoming tour dates. "This is what I call the perfect ending of a touring cycle. Finally, we are arriving in Eastern European and South American shores this fall. I know it's been ages…and I know there have been legions waiting for us…on behalf of the band I must say though: the wait is over; we are coming back rejuvenated and hungry! See you all very soon!"

Behemoth have a month-long break after their Aug. 17 tour date in France, which the band will use to begin rehearsals for their new album.
