Due to Tony Laureano's (ex-DIMMU BORGIR, NILE, ANGELCORPSE) touring commitments with ALL THAT REMAINS, he is unable to join INSIDIOUS DISEASE (formerly INSIDIOUS) for their two German shows this week. His replacement for these performances will be DIMMU BORGIR/ex-VADER drummer Dariusz "Daray" Brzozowski.

INSIDIOUS DISEASE will make its official live debut at this year's Wacken Open Air festival, set to take place July 30 - August 1, 2009 in Wacken, Germany. The band will perform on the W.E.T. stage on Friday, July 31 at 11:00 p.m. A warm-up show is planned for July 30 at the Magnet club in Berlin, Germany as the support act for CALIBAN. INSIDIOUS DISEASE will also take part in a meet-and-greet at Wacken on Friday, July 31 between 6:30 p.m. and 7:15 p.m. at the Metal Hammer fanclub stand.

INSIDIOUS DISEASE recently posted another new song, "Nuclear Salvation", on the band's MySpace page.

INSIDIOUS DISEASE's long-awaited debut album, tentatively titled "Shadowcast", was mixed with Russ Russell (NAPALM DEATH, DIMMU BORGIR) for a late 2009/early 2010 release via an as-yet-undetermined record label. In addition, the band has recorded a cover version of the DEATH classic "Leprosy" as a tribute to "one of the greatest metal bands ever," according to vocalist Marc "Groo" Grewe (ex-MORGOTH). He tells BLABBERMOUTH.NET, "The INSIDIOUS DISEASE version is not denying the original [since it] can't get any better."

INSIDIOUS DISEASE recorded 12 songs for its debut CD at a studio in Norway with producer Terje Andersen (a.k.a. Cyrus) of SUSPERIA.

NECROPHAGIA frontman Frank "Killjoy" Pucci has co-written and contributed guest vocals to a cut called "Rituals of Bloodshed" which is included on the album. Other songtitles set to appear on the CD include "Conceived through Hate", "Desire" and "Insomanic".

INSIDIOUS DISEASE is:

Marc "Groo" Grewe (ex-MORGOTH) - Vocals
Sven Atle Kopperud (a.k.a. Silenoz) (DIMMU BORGIR) - Guitar
Shane Embury (NAPALM DEATH) - Bass
Tony Laureano (ex-DIMMU BORGIR, NILE, ANGELCORPSE) - Drums
Jon Øyvind Andersen (a.k.a. Jardar) (OLD MAN'S CHILD) – Guitar

In an interview with U.K.'s Terrorizer magazine, Silenoz described INSIDIOUS DISEASE's material as "a good variation; a good mix of groovy, downtuned stuff, but it doesn't sound too modern, it's more back-to-basics. It's not really technical by any means, like some people might expect, it's more heavy riffing, attitude. It's hard to explain, but it's safe to say that the word 'extreme' would cover most of it. We have fast stuff, of course, but we also have slow stuff."

Regarding INSIDIOUS DISEASE's influences, Silenoz said, "Not anything specific, but me and most of the guys in the band, we grew up with the '80s extreme stuff and I think that shines through the music but I wouldn't say that we take any direct influence, it's more that feel of what was going on in that time in the late '80s. That quick and clean production on everything loses its charm so we tried to make it sound as analogue as humanly possible to digital recording."
