Metal Vocal ensembles. How to record solo?

I'm back. Dude that is awesome. I love it. Reminds me of old Ministry a little. I'd love yo hear it again when you get all the vocals you want in. Here's an idea. Go buy a harmonizer as legba said at Guitar center, use it then return it. :D

i've seen this discussed before, i think originally these gang vocals were done by getting 10 guys to shout into one mic in one room. i'd imagine that'd get the most authentic sound. if ya cant get 10 guys, maybe get one guy to do it 20 times through one mic.
