This is in relation to their stuff up to 1995, which was when i was introduced to them. They changed singers in 1995 and to be honest I never knew this until it was pointed out to me a few days ago. That being said, I found it very difficult to get on board with CC because of their old singer.

Cannibal Corpse has been around for a long time (since 1988) and they have 14 albums with a total global sales of over 2 million copies. It has been stated that this makes them the best-selling death-metal act of all time but I question the validity of this. It is difficult to tell with death metal because there are so many sub-genres and arguments over who goes into which category that even fans like me have a difficult time keeping up with all the various labels.
The reason why I didn't care much for Corpse is because their vocals were just boring in my mind. Their old singer Chris Barnes had an extremely low pitched voice for death metal. He was the Barry White of the un-understandable lyrics world. With other acts you have a chance of understanding some of the stuff and that is part of the fun. There is no chance you are going to understand anything Barnes is singing and it simply ends up sounding like Cookie Monster mumbling (which is what his vocal style has actually been compared to)

They also had rather far fetched and kind of disgusting lyrics if you ever bothered to look into the album sleeve in order to read it (because there is no chance you would know them otherwise.) I definitely needed to hide this album from my parents because they certainly would have had a problem with it even though I didn't know it was going to be like that and i would likely be wrongfully accused of doing something bad had my album "Tomb of the Mutilated" been discovered.
Here is a sample of one of their better songs for you to get an idea about what it is to have Cookie sing for your band. This is arguably their most famous early work.
So there you have it. I am not afraid to say that I do not like their early work at all. I tried to and they remain legends of Tampa to this day. Now that i have learned that they changed singers in 1995 perhaps I will go back and give a few of those albums a listen.
