Invoker was born late 2003, from a distinct will to provide an acid combination of Satan, alkohol and disrespect.

The lust to create a soundtrack which fitted the band as a lifestyle, only transforming cult acts of Alkoholik Malevolence, disrespect and ugliness into music, was indeed the primal point for Invoker to go into this kind of raging abuse.

The trio which surrounded Invoker, namely HellRokker (drums), Warmaster (bass guitar) and Nekrobastard (lead guitar, rythm guitar, vocals) converged to the same point : fukkin' thrash metal to bring the masses into total and absolute madness, hearing some loud and pounding rythms, chainsaw hammer guitars and a bass sharp as hell.

Wielding the same standards of bands like Kreator, Nocturnal Breed, Nuclear Assault, Aura Noir or the mighty Sodom, all three members began to compose and rehearse to serve the first assault : "Initiate Mind Regression", a thrashing holokaust composed of 8 tracks in the sole Invoker style, evoking some aspects of what we could call "hell on earth".

During year 2004 the first trio line-up got the people drunk and mad during some thrashin quote metal gigz and the first release, "Initiate Mind Regression", has been released by Forgotten Wisdom Productions. After some gigs, a fourth member, Conqueror, has joined the band as the second guitarist. So, the band spend the year 2005 to playing in concert and composing the second album and the "Hate Corp." split CD.

In year 2006 HellRocker decided to leave the band after the recording of "Hate Corp."
