The first time I heard the terminate damnation album I was like, yessssssssss thats the sound im looking for. I like the physics of fire, but it got kind of annoying how all the clean vocals only talk about fire. I thought dichotomy was an all around good album(not as good as terminate though). I have nothing good to say about the celestial completion. I am is good, I kind of like the direction they are going with that album. I do kind of miss jason wisdom, but the knew vocalist is still really good.
As for original members, they don't have any from their formation but if you count original members from their first album seth hecox is the only one left.
