I was going to post something similar asking about this, and I have a weird thing that happens, sometimes when I try to growl/sing in the way of Mikael Stanne, I usually get hiccups!!
I have no idea why.
At first when I tried to growl like him I couldn't manage it, but I find that it gets easier the more you do it. Each time when I have a go, I have to get 'warmed up' before it sounds reasonable...it's like you have to get the right mix between growl and adding a hint of vocals in there as well.
I've had no vocal/singing training, so I probably sound crap, but I've nearly got the style of Stanne.....lol....yeah right.
It's like, I can get the style, but there's no point coz I have a crap singing voice anyway.
These damn hiccups though......
Also, how do you NOT ruin your throat? lol, I couldn't speak properly for about 5 hours once, it felt like my voice was breaking all over again...I need water!! lol
I have to say that Mikael Stanne has the most articulate death metal growl I've heard yet, I was listening to Shadows Fall, and the lead singer of that is nowhere near Stanne. Also the lack of electronics/piano makes it so much more mundane....?!
