1. Black Sabbath/Ozzy
2. Iron Maiden(Bruce Dickenson can belt 'em out)
3. Danzig(Danzig has one of the best voices in Rock n Roll EVER IMO)
4. Gun's N Roses(They are harder than Poison, Motley Crue, and all those other hair bands)
5. Slayer(started in the late 70's and still touring today)
6. Pantera(These guys put bands like slipknot and mudvayne to shame)
