Take some opera lessons.

They will definitely inspire you to set and reach for lofty goals, or at least they did me. I don't exactly sound like him, but when I decided I wanted to really be able to sing (and not just whine like King Diamond

) that was who I had in mind. But, I have had a few people tell me I sound like the singer from Fates Warning, and I would always say (being a smartass), "Which one?"

(They always say Ray Alder, but I prefer FW's original singer, John Arch, myself.)

This was from 1998. (4 years after the previous one I posted. It was recorded live - I was playing drums and singing at the same time. This was still before I took any vocal lessons, but I had started singing lower in my register. If you listen with Winamp, I would set the EQ flat, but pull the 170 and 310 and 600 filters down. - This stuff was bass and low-mid heavy. I use 28" Kicks, and had them tuned fairly low at the time, and the bass player was playing through eight 15" speakers powered with 3,000 Watts. He was over there trying to not laugh and keep playing because the nut on the guitarist's guitar broke, but we kept going no matter what. I'm glad we did, because this was the only time this song ever made it to tape.)
