avenged sevenfold

I'm kind of wondering if there's a trick to it too. As far as I know, the only trick is a willingness to destoy your vocal chords, but I've got my fingers crossed that there's something I don't know. BTW, good choice for your thread title. You got me to click. :D I saw those guys a while back. Great show.

How does AC/DC does it ??

I think he just sings really high and makes it a little breathy.

We're talking about the other kind of screaming though.

I don't know either but you have to train yourself like anything else. I think I read that it took Aaron Lewis of Staind awhile before he could do it. He had the same problem. Now Staind isn't as heavy as some of the bands out there.

Ok I used to be a pretty big Linkin Park fan, and while they are not exactly as 'heavy' as other, Chester can scream pretty damm well. From an interview:

"According to Chester, the reason he can scream like he does now is that when he was young he used to sing at the top of his voice around the house all the time."

So I guess its like most things: If you practice you'll get better as your vocal chords develop, so the best bet is probably to start singing loudly a lot, and take it from there.

I think after you devastate your vocal chords enough, you can scream like they do through constant healing and re-healing.

I wouldn't recommend it, unless you want to end up like M. Shadows, and barely be able to speak after shows - use your natural voice, put a little bit of edge on it, and tell anybody who wants you to scream to bugger off!
