also there's:
Robert Plant - He's One of a kind.
Ronnie James Dio
James Hetfield
Timo Kotipelto
Tobias Sammet(i think that's his name) - The singer from Edguy, very Dickinson-ish
Michael Kiske - Helloween, feakiest voice ever, pretty cool
Ronnie Van Zandt
The guy from Sonata Artica, can't remember his name
that's all for now
To improve technique and of course trying to keep all as clean as possible. I know my own limits and speed limits and so on I never play anything I'm not capable of. That wouldn't make any sense. After three years of playing I tried to play everything as fast as possible and that sounded, I would say, like shit, and I didn't realize that if I'd play bit slower things than I was capable of playing then everything would sound much better.
