They have have been around for over 20 years but have never played at OEF yet!!! In their own words they had to learn to play!!! It is none other than Czech perverted gravediggers and deviants called AGGRESSIVE TYRANTS!!!

In the 90's, this band left a deep scar in the Czech underground scene with their demos and unforgettable gigs full of fun, porno lines and other perversions harming no one though!!!

AGGRESSIVE TYRANTS have gone through style changes and tended more to the hardcore style for a while but have returned to the proven grind core noise!!! And that suits them best! We all will have the chance to allow ourselves to be convinced at the Battlefield!!!
