I'm a huge fan of Seether, and Shaun Morgan's voice. I can play quite a few of their older stuff on the guitar (Gasoline, Diseased, Sympathetic ect.) And I'd love to be able to play and sing a few covers. I can't get the harshness in my voice as Shaun can while singing, I can scream without hurting my voice and it sounds fairly decent, but I just can't sing in that raspy kind of voice. I'm working on covering Sympathetic at school next month, and I'd like to improve my singing before then. Any tips?
