Hey, I've noticed recently theres been lotsa talk about how to growl and sing in similar ways to Opeth and a couple of people have said that Mikael growls very quietly. I understand how it's easier to do it quiet as long as you don't have a dry throat but when he does it live it looks like he's growling incredibly loudly and with lots of force. I was just wondering if it really is quiet or not, I was also curious as to if there's a volume difference between his growl and scream...
