Horrendous are not horrendous. In fact, I'd say they're the complete opposite of the definition. Ontological Mysterium is quite a bit different from Idol, it's still largely progressive, yet really different. The pace is much quicker and very thrashy in sound. And Horrendous utilize that sound masterfully. Not sure if this quite surpasses Anareta as my favorite from these guys, but yeah, album is a fucking banger.
