do you mean the background vocals, the group-shouting: BOUNDED BY BLOOD! of the lead vocals.

The lead vocals are often dubbed by the vocalist. There is also a lof of reverb on the vocals. The ground-shouting (lack of a better word for it...) is just a lot of people shouting, nothing more....

hope that helped.

you're welcome...

I don't know if you want to try something like that yourselve... I wouldn't do it to the same extend they did. It is really an 80's sound... Not really up to modern standards...
