With help of Doc (Vader), Novy (Devilyn) and Hiro (Sceptic) the band prepared material for a full debut album.

Titled Immolated, it was produced by Szymon Czech, and graphically designed by Jacek Wisniewski, who had been previously responsible for several Vader's cover artworks ("Kingdom", "Black to the Blind", " Live In Japan").

Following the promotional mailing of Immolated the band received a number of contract offers from labels from Europe and the United States.

Finally, Dies Irae signed a four-album contract with Metal Blade Records, which represents the band around the world except Poland and Japan.

The debut album was released in November 2000 and its promo campaign was backed up with a video-clip for the track "Lion of Knowledge".

During the "Empire Invasion Tour 2004" they played alongside bands like Hate, Lost Soul and Esqarial.

At the beginning of 2005 at TV Studio Dies Irae shot a gig for the forthcoming DVD release and in February they hit the road along with bands like Decapitated, Hate and Crionics in "The Ultimate Domination Tour 2005".
