How many extreme squads from Central America do you know? Not too many, right? Well let us introduce you to Costa Rican quartet, HERESY.

Although they are still quite young, they have achieved considerable success in the international thrash metal scene!!! Formed in 2011, they have already produced two full-length records and several singles and EPs.

Because of this, and their endless gigging in the local scene, promoters couldn’t help but take notice of them and consequently HERESY has landed gigs in their home country as the opening act for amazing bands such as Sodom, Testament and Metallica. Even with all that going on they have still managed time for some epic Europe tours!!! There’s no doubt that their passion and devotion to music makes these guys really special, as we will be able to witness ourselves on the boards of OEF 2020!!!
