They perfectly encapsulate what death metal just is and that's why I still consider them a world class band despite not necessarily being a fan boy myself. It's hard to even classify them as old school death metal OR brutal death metal because they're simply both and I'm not sure that anyone would even argue with that.
I just think there is more interesting shit that was done in the subgenre as a whole but I've been far more keen on Corpsegrinder era CC than I used to be. Bloodthirst is a masterpiece.
