Thread: How to get really brutal screams like Disfiguring The Goddess, Ingested and Devourment?

I listen to their songs, and whenever I try screaming like them, since I can already do growls, it just doesn't work. Big Chocolate from Disfiguring The Goddess had a "tutorial", but it ended up being him eating ice cream, and I get the play of words there.

So please, anyone, how the hell do I get those pig squealing, low brutal as fuck growls?
As usual, someone has to take the piss out of a question like this.

Drop bricks on your feet. That makes me scream really well.
