Ok, I've been honing this for a few months now, and I can get my vocals about as gutteral as Chris on Butchered at Birth. (at least, more than Eaten Back to Life). However, this doesn't last too long, and I've also been trying to add a bit more power like Corpsegrinder lately. Is there anything I'm doing wrong here? What should I do to mantain a good vocal style for some time?

Thanks.

just keep workin on it. it'll be louder for longer if you keep doing it.

checking the various other growl vocal threads could help too

and listen to as much gorerotted and lordgore as humanly
possible.
