I don't own any of their albums but I grew up with a few kids that were big into them. They're really good and Chris Barnes is a death metal god. I remember the first time I listened to them and on one of the tracks my friend claimed they were using a brillo pad as a guitar pick...my reaction was "Whoa." (I was going through a Keanuu Reeves faze I guess)
I've always thought of Cannibal Corpse as Gwar without any fucking sense of humor. Music is OK for the genre, but not anywhere near as good as say Morbid Angel or early Sepultura.
And I will show you something different from either Your shadow at morning striding behind you Or your shadow at evening rising to meet you; I will show you fear in a handful of dust.
