I wanna record some chants like in BFMV's Scream, Aim, Fire or like off of Atreyu's new album Lead Sails Paper Anchor

How many people should I need to do this?
Well, for the chant on Machine Head's "Clenching The Fists of Dissent" the "Making of-" DVD shows them recording with five groups of around 5-6 people.

The more the merrier, I guess.
Ibanez S470 (EMG 81/S/85)
Sigma DMC-15E
Laney VH100R
Laney 4x12 Cab
Ibanez Weeping Demon
M-Audio ProKeys 88
Mbox 3 Pro
KRK RP6 G2's
Plum Team FTW!

You can do it with just like 2 or 3 people
Just record several sections and mess with the pitches of each recording, knock them slightly (i mean slightly) out of time with eachother and stuff and play around. It won't sound as authentic as it would with LOADS of people but if you only have a couple of people you can still pull it off
